As you may have noticed, the current round duration has quite drastically changed in the recent months, up to the point where there is a 12:50/13:30 rule.
Either the marines win by 12:50 by taking out the hive, or the xenos win by 13:30 at Almayer.
This is far shorter than the usual, considering anything going far past the 13:30 mark is exceptional.
Having such short rounds is both not very fun and presents some major problems to the enjoyability of roles such as doctors, who are unlikely to get to do much beyond the initial prep rush, after which medbay sees minimal use until the final evac. We're already having Req where there isn't all that much to do after the rush, and now I find doctors facing similar problems.
Personally, the combination of decisive short battles near the start of the round, after which it's all over for one side (usually marines), and that it's impossible to really play the roles in the darkest hour makes the game very unenjoyable.
And, as everybody probably knows, mutators are the likely culprit for this decrease in fun. No longer will you fight for your life in a final stand, holding back the xenos until you eventually die. You just get killed immediately and the marine force around you is routed with no chance of body recovery.
This is extremely frustrating and boring.
