they should leave iron citron as he is
and only change his iron mode damage that is the only problem with him
once he gets into iron mode he is insanely OP they should make his shots do 40 damage instead of 50 just while in iron mode
other then that he is fine
i mostly use him as a sniper to annoy the zombies
the shots are hard to land from far and they only do 25 damage which is nothing in this game and he can only shot once per second 25 damage per second is nothing
up close where he does 50 its also only 1 shot every second
and if you miss it you do splash only so its kind of a high risk high reward
they should leave him as he is and only change the iron mode which is too strong for sure
