For Warmane i mostly just use Hotkeynet with my own custom script with specific command chains it runs for specific character groups like Shamans or healers or ranged/melee DPS, yada yada, i even used to run this 25 man group off my fucking netbook with a program called Rendering Disabler. Run the script to log all my accounts into Warmane then get them into group/raid/click the summon portals, then disable the rendering to get the netbook to run perfectly fine 25 mans.

Horde cried for years on the forum about me shutting their shit down and finally they had a new rule enforced that you can only have 5 accounts within 8-10 yards of each other or they drain out of mana then health and die, but i get around that shit by just running delay and position commands in my scripts. That only applies to the outside world, you can still run the maximum number of characters on top of each other inside raids/dungeons.
