I hate Isida because of it's extra ordinary healing powers and ruining the CTF games with very high score and stealing all battle fund without doing much. The most hard part of CTF is capturing flag in tough battles which is unlikely can be done by isida.
It's a great weapon but if a low rank heals marshal he can get 1000 score in just few minutes and usually high ranks and marshals leave that battle if they see isida with too much score.
Developers please look into this matter maybe decrease amount of score isida get while healing. I read in Tanki 2.0 we can allow specific weapons and tanks for battles.Then, I would never allow isida in my battles
I find freeze most annoying cos I play against loads, and especially when your on a flag run, they just freeze you to death even if they are doing "no" damage i.e. m0 freeze. I just hate that wep
