Thanks for all the replies.

I ended up with 4 accounts in hopes to get better loot. Apparently the game still have streaks of raining with legendary and nothing for a couple of rifts. So far I have 4 WDs and 4 Wizs. Am tempted to try 4 Crusaders too soon. The issue is the usual, some of your members stays in the back (like looted something or got attacked but for whatever reason stops) or goes berserk and rushes ahead like an idiot.

4 Wizards are easier on trash white mobs and elite packs (save those who have nightmare and knockback, along with vortex and other knockback/pullin stuff) but suffer a little on single target bosses. On the contrary WDs are pretty much the opposite with Pet build. Am tempted to try a dot build x3 with 1 pet build but those needs to be more mobile to be effective. Will see.
