Its fast paced. I like it, but I don't at the same time. Best reasoning would be the first time I played, the 3v3 went by too quick, we got both altars, and then it was GG from there.... I as Riven went 18/1/9
the second time I played, altars went 1-1, and was squared for the next time as well, but then enemy team got both altars and my team went down quickly......
what I started thinking during even that first game......... these altars are released too early, what if they kept these locked until say a 3 minute mark, or a 5 minute mark? and then also, what if for an extended period of time, after the "buff" you get from owning the altar is gone, there was an additional cool down placed where no team had the bonus from an altar regardless of who owned the previous one?
Its just an idea.
Benefits from what I can think of my thinking:
1) it would allow more time for laning, which would keep purpose for laning
2) 3v3 fights would indirectly be "scheduled", which then would also allow both teams the opportunity to risk recalling in time to prepare for said fights.
Just one Summoners thoughts....
Remember..... It only takes most, to make the majority...
