Ghost Pepper is what I've read too, I keep thinking it'll be Hypnoshroom or a tiny little Dandellion?
Even if they do give it to a new character, to me still most of the characters will be redundant and pointless to use. Soldier is still a great class but because the other zombies are so much better right now hardly anyone is using them.
In my opinion, from adding friends, and younger kids who have added me through the first game and the second, most of them have maxed Rose, and Electro Brains, most of the younger generation are playing all the broken classes, you can't blame them.
I feel like it is the more mature and experienced gamers who are playing Plants and struggling to combat the little kids, due to no fault of their own it doesn't even matter what class you use or how good you are most of the time. Zombies are capable of, generally speaking much higher vanquishes and streaks. I have no problem with losing, or even dying, but when you're dying to the same thing over and over again and you don't even stand a fighting chance that's when it's frustrating and that's what is driving players away.
Rose was broken, but so were some of the zombie classes, Rose is still great to use if you want to come onto the battlefield and say 'Ohh yeah, I'll slow that thing down and turn him to a Goat, then I'll die because my job is done.' Once your CC is gone, you're done. Any class shouldn't be so reliant on CC, none of the zombies are like that, the ones that are all hit like trucks. Someone recently mentioned that her CC should have been nerfed, and not her hitting potential, I'm starting to agree with that.
Slightly decreased damage and reworked CC would have fixed Rose, right now she's garbage and I'm not looking forward to levelling her up. All of me wishes I had played her non stop when she was broken but that really isn't my style.
