PVZ GW2 Bugs/Issues I Have Noticed

Okay so let me start this off by prefacing that I used to play this game a bunch on my Xbox when I was younger, there weren't any bugs or issues like this when I used to play. Now that I am playing again on my pc I have noticed several big problems, one being how much lag the servers have, I mean this when I say it but I sincerely believe the servers are almost unplayable, I mean I will rubberband into a ZPG when I am  VERY far away from it. Also when I play any game whether its mixed mode or turf takeover I will level up and not receive any of the levels upon returning to backyard, I still keep the upgrade if it is put on a character but this is a serious issue. Another problem is the amount of hackers/cheaters there are in the game, I will run a game of turf takeover and suddenly everyone is invisible and gets one shot by ANYBODY in the lobby, making it some weird invisible one shot gamemode that just sucks and ruins the fun for most people. I've also ran into many MANY people playing as bosses from the backyard/garden/graveyard ops, this is a tremendous issue as it ruins the core aspect of the game, like how am I supposed to push on great white north as a zombie when they have a mystic flower boss and spawning in the extra mystic flower AIs. It makes the game much more difficult to play and its usually if not almost always another person playing as the boss. Another thing mentioned recently within the community is people getting levels added to their characters via a script, the people keep these levels but they don't get the upgrades, this is a really big issue because they could end up falsely banned for something they didn't even do and it ruins the gameplay for them since they can't even level characters or get their upgrades. The big thing people do and the big objective in most peoples eyes is reaching rank 5455 by mastering every character and this script is ruining the whole point of it. Please Electronic Arts and please Popcap do something about the state of this game, as there has been a huge influx of players due to the popular streamer online known as Jynxzi. The state this game is in is truly heartbreaking to me as it has been a long time favorite of mine and millions of other people worldwide.
