Just happen to be on vacation, so managed to play ~40 games up to t4 US and jap lines. First time playing, controls etc feel really solid, gameplay is quite addictive.
As some have said, a little variety is needed if it wants to retain the playerbase in future (maps, weather.. whatever)
Spotting system i don't understand at all.. sometimes tanks just appear 16km away, guess they fired at something? Destroyers pop infront of you within 3km and you have torps inc, no way to avoid them in battleship at that range.
I can see this game evolving into some kind of camping sniping behind island stuff in future. Playing aggressively, which for me felt really fun in t1-3, does not end well at all when t4-6 ships play (same as WoT i guess). You will have torps + volleys from anyone in range coming in making you a sad broken ship.
Some mechanics are really cool, getting propeller / driving gear blown out i ended driving LOOOONG straight line into an island, and then getting stuck to said island, man i did get stuck a lot.
I guess most of my complaints are regarding balance and that can be easily sorted when more and more people play.
Overall i can see myself playing this in future, for sure.
