Press H to see your personal "Buff Counter". As for an indication of what you get from circles I am also missing that. There were Icons on the Test Server. Please bring them back.
Otherwise: I LOVE this game mode!
General impression: looking forward to see this on the live servers!
Also, the given missions made me dabble with higher tier French crusiers for the first time and I was positvely surprised. And yeah, the reload gimmick really is just a gimmick ;-)
