Soo got to tier 4 (Isokaze) and BB line (Kawachi). Beta exp rates(?) OP.
Destroyers are fun! Betting my life on a sneak attack feels great when it works, except for occasionally when I sneak by an island and suddenly an enemy DD is here and they follow me all day lighting me up for the entire enemy fleet >:C DD slapfights near shore lines are hilarious, one tiny patch of sea like 500 square meters wide, four DDs enter, only one comes out alive. Where running aground becomes a gambit.
Battleships (just the Kawachi for now, really) takes some getting used to. Finding a good place to be that strikes a good balance of not making you in the line of fire of everyone, ever and not taking the entire match to get to is hard. Though when the time comes to start punching things with artillery, it's great! Citadel hits are obscenely strong (I think it's like an AP shot to the lower center of the hull?), and apparently not many people ever expect me just turning my Kawachi around and pounding them with my other guns while the first four are reloading :V
Cruisers are nice most of the time, juking torpedoes and shots feels good until a BB shows up to wreck the fun. Just got Tenryuu as my first cruiser with torpedo, and multitasking both weapon types is hard.
Carriers don't look terribly exciting, but worth a shot I guess. I just hope it doesn't net me the same amount of appreciation as a WoT arty player. People are already complaining furiously about torpedo bombers when they do mediocre damage and can't land like more than one torp per salvo if you pay attention - v-
