So not true. 3v3 is not about unit massing, its more about strategy employment thru units and how you RUSH. First off, CCing is for wimps and it wont help. Second, even if my allies aren't gonna harass with me, I still do it. Sometimes, they tech and the enemy is so distracted with me I end up buying htem the time we need. 2on2 and Solo is about strategy employment with the units you have, espeically when many players are soloists.
Bears are not hard either, I have done bearads before and I have faced bears plenty of times. Hell, I onced won a game vs bears and all I had was foot sorcs. Alchemist with the acid really helped in busting up those furry bastards. Managed to get gryphons in time though.
