[Gameplay] * Gunplay/gun balance and the importance of sound were the best characteristics of PUBG - the high frequency of level 3 armour and the constant noise from planes, flares and red zones completely ruins that (SRs are now much worse, SMGs are ineffective). I thought flare guns can be a fun part of event mode and not more.
The big advantage of L3 gear leads to too many early fights with low player numbers for the rest of the match
If you fire a flare gun, I think you should get a drop. Even if you shoot it right when the new timer starts, you often don't get one because everyone fires theirs at the same time.
[Spawn Rate] * If you insist on keeping it on live servers, I think there shouldn't be more than two in a map and there should be a high proportion of games where they are never found.
[Sound] * Planes are too frequent and loud, footsteps are too hard to hear for several minutes every game.
[UI] * I don't think the indicator is necessary but I'm not sure it matters too much.
