The new MCH likely carries old unfixed issues

Yeah, I was rewatching Mrhappy's video with the machinist and he actually manage to only get 5 heat blast on wildfire. And in that case SE should indeed adress the issue, either they balanced the skill thinking it should fit 5 heatblast and gave a very generous window that'll probably be exploited by players with a good ping and some skill speed to put an extra one. If that's it I feel like they should either reduce the timer to 7s to make sure everyone get 5 on it. Or they planned to have 6gcd and thought 0.5s to fire the first shot was enough and really overstimate how responsive the game is. In which case they should add 1s to the timer of overheat.

If it's made on purpose to have different result for "skilled" player, it's dumb since the only skill involved would come from your connection to the server.

Hopefully they already noticed this and tweaked it.
