These things are indeed random, but sometimes random things develop into what appear to be patterns, just like a winning (or losing) streak at the casino. Also, I'd figure that patterns might also be sometimes built into the random generation, for example one of the "random" things the game might be programmed to throw at you is to repeat something several times. A few thoughts:
Are you playing solo ops? If so, are you spawning AI team mates? They ought to be able to handle the boss waves pretty much on their own with no input from you. When I began playing, it took me a while to figure out that I could spawn my team mates, and how to do it. If you're not doing solo ops, consider doing so. If you're doing solo ops by yourself with no team mates, it's gonna be extremely difficult at your skill level. Solo ops on easy difficulty is how I developed most of my initial skill with this game. I recommend you go back to easy difficulty until you improve. The difference in coins earned is not vast and the XP is the same.
I don't know how to put this part without seeming unkind: the bosses on normal difficulty are really not that hard to defeat. You need to improve your skill. I was there once myself, and for quite some time too. But I can easily finish off a super boss wave by myself, it is simply a learning curve. Aiming, utilizing cover, knowledge of how to play the various characters and variants, situational awareness, knowledge of the maps and the AI behaviors - these are all things that you will get better at with practice. I would offer to play with you and show you how to improve if you played on PS4. I recommend you seek out some garden and graveyard ops gameplay on youtube or twitch and you will pick up lots of tips and ideas just from observation.
Here's a couple practical examples: the Yeti has an icicle attack. If you are under cover, it can't hit you. Regular gargantuars pretty much can't do anything to you if you are on a rooftop. Stuff like that.
As a fellow oldster, I can tell you the learning curve of a game like this is much steeper for us than for young people. I can totally sympathize with your situation because I've been there. I used to suck with a capital S, but after a year plus a bit, I am now of moderate skill. My seven year old daughter is an ace at garden ops, though she's only played enough to be level 200 something. The only reason I get to be better than her is because she doesn't play regularly!
Lastly, you will have a much higher chance of a super boss wave if you plant an enchanted garden. So I'd avoid those if the bosses are proving too difficult to defeat. Take your time and don't be afraid to run away during a boss wave to heal up or find a more advantageous position. There is no timer and you actually earn more coins the longer the game is prolonged.
thankyou for the reply. i have been sometimes using the enchanted gardens but not always. i had wondered if that makes a difference in boss selection. i did call the EA support team yesterday and followed their instructions regarding troubleshooting to determine if the situation with the megabosses constantly getting selected was a bug or not. i uninstalled the game completely then followed instructions to clear mac address and clear persistent storage 3 times. then i reinstalled the game and played again today. thats why im just now seeing these responses. the result appears to have been mixed though. for the first several hours of gameplay after following their instructions, it was still giving me megabosses every single round 10 boss fight. if i was on zombie team the mega boss was super bean. that was indeed different from yesterday though because yesterday and for a day or 2 before that it was torchwood on zombie team boss fights. today, on plant team boss fights it also always gave me a mega boss every single round 10 boss fight, but the bosses were always different megabosses. for example, there was a megaboss vampire, a megaboss electric dude. finally withing the last hour, it seems to have stopped doing this to me for the time being. i think it got somehow triggered to stop when i reverted back to easy difficulty level to experiment and see if it would keep happening. it did not happen on easy. then i went back to normal. the boss fight for round 10 on normal was no longer stuck on megaboss. so if this is indeed a bug, which the EA support people told me they think it is, then the possible fix is to revert to easy difficulty level for at least one round of garden ops then go back to normal difficulty level. not yet sure if this method is just temprary or permenet.
as for the skill level issue, i can concede the point that im probably not as good at the game as other people are. there might be stuff i dont know about the game yet. perhaps looking at videos would do me good. but it still seems odd to me that the game would be geared towards young kids but have game mechanics this complex. i wouldnt mind you giving me a how to session but im on xbox.
ive been playing mostly on normal difficulty setting, usually play solo garden ops, i hop back and forth between all the character types because i like to level them up for the coins. when i need extra help, i plant heal flowers and gatling peas when i have them, and rocket bots and dr heals when i have them. i feel like my play style could be called aggressive. i do get up close a lot of times. but i also do try to run away and heal when needed. i find it more frustrating that the ai for the healer characters dont always want to heal me. ive literally been down to 3 points of health standing next to a heal flower character as it kept fighting and ignoring me and let me get knocked out. that happens a lot. but when the ai seems to be working alright, the heal flowers/scientists do help. i usually hop around between all the different characters in order to level them up for coins. then i take with me into the garden ops at least 1 tank like character and 2 healers.
