Melee Cleave Optimization

Hello,

i am multiboxing with 4x arms warriors and 1x holy paladin at around lvl 19.

Now I am considering to add a second healer in the team for one of the warriors for more flexibility later on. Anyone drive with 3x arms warriors, holy/retri paladin and a priest? In many Threads I have seen 3xW & 2xP - but I worry that I loose to much dmg - and also if it possible to heal the hole 4 warriors with only one paladin.

What are your experience so far with melee cleave - any suggestions you gained through leveling phase? Have you played it until endgame or just switch to a trinity group ?
