Ok so I played with smoky, thunder, vulcan, rico with viking and mammoth.
Smoky: this turret is quite weak now and not fun to use anymore. The fun part was the damage the critical hit dealt but now too low. I liked it much more when it was unpredictable; made it interesting to use.
Thunder: This is turret is balanced. In fact, I like it more now.
Vulcan: I still find it OP. The damage it deals should be decreased as well as its impact force.
Ricochet: This turret is a little OP too in my opinion. The balls travel very fast and with the damage it deals it becomes a little OP. Also, it can fire many balls without needing to reload. I think it should deal less damage or fire less balls without reloading.
Viking: This is much better now and balanced.
Mammoth: This hull is a little better. I believe, that it's fine.
