I think its time I drag up this topic again even if nobody seems to care about it.
This is only a factor when the first team doesnt manage to set a time and have the biggest impact on C4 maps.
In short if you attack first and the last objective you do is a C4 objective you have 15m50s on you to complete it and when the last objective is a delivery objective the first half is 15m04s.
If you attack second when the first team didnt set a time you have 15m on you to complete it. (yes, you can have a little more if you defuse in overtime but then you afaik only get the time up to the point of the defuse and not the full time needed for it to blow up.)
Not saying it needs fixing before season 2 and possibly delay it more with new bugs but at least acknowledge its a problem that needs fixing.
