I pretty much agree with the OP (theonz)
I too am a level 233 player and think that The Berry shooter AND the nerfs to the other characters has really unbalanced this game now.
Whenever i play on the plant side i always play the Pea as it generally easy to play from sniping on rooftops to suicide missions against the engineer and his portal. This new Pea makes it way too easy to block the zombies progress and 2 of them playing more of less together are very veryt difficult to tackle.
Imagine my surprise in the games i have played to find upeards of 6 Berry shooters! Not much fun in that and this game used to be all about fun.
With a bunch of peas defending the garden zone i used to switch to the Chemist. Ermmm not any more it seems. 8 shots, a very slow throw of sticky bomb and you need to get close and have a decent aim on the the most mobile character in the game? I struggel to get anywhere near the Berry pea and even if i do take him down i am so low on health that i can't take on another character.
I would suggest removing the nerfs from all the other characters, even the camo cactus. (In my experieince it is rare to find a good one of those anyway)
