removing scouts from viral is definetely a good idea (quite probably the first good idea i`ve heard dreamland lol)
imo collectives are fine as they are thou, i played em for 400 days at fast, and mostly fought battles between 1 and 3 mill pr, not all that low for fast server...collectives are of course worse on faster servers, but the same goes for maru`s...On slow collectives and marauders holds aprox about half the power on the server, of course not counting by planets, but by capability to fight.
In the 7 MK uw attempts collectives have been the biggest hitters although most active empires are terran.
on a server like rt collectives of course get shafted big time as people have turn to just keep spamming you if they fail the first time, where on slower servers a battle mean alot more...if you lose your fleet, you aint getting a new one that day less you`ve saved up turns for days heh
