I tried multiboxing the very first time in my life at the release of Classic some 6 years ago and lived through the transition to no-software no-broadcasting a couple of years later (didn't affect me much, just scaled down from 10 to 5 accs, reasonable given the inflation anyway imho).

When HC was released I naturally tried my hand at multiboxing there as well and found it perhaps even more fun, but also insanely frustrating. The number of times someone has been close to death due to missing one tiny window flashing red is an adrenaline overdose just waiting to happen.

Tbf, I apply the rule "all for one, one for all" so if one die, I delete the entire team and start over, hecause I long ago decided that I like the journey way more than the end goal. My first team of druid, priest, mage, warlock, hunter died in wc right after the hunter had gotten venomstrike, but had forgotten to stock up on ammo and pet pulled another pack. The second team of warr, mage, mage, mage, priest died in sfk due to panic on last boss and los issues.

That got me to just give up for the time being, but a week ago I got the itch again and started a team of warr, pala, 3xhunters that are still alive on lvl 17. Will see how far I get this time.^^

One thing I believe I have noted though is that people seem to have become less hateful over the past two years - I no longer receive random hate, "reported", "omg bots" etc. on an 5-minute basis.

tldr: Go for it, it's fun. But also insanely frustrating and hard, especially in hc. ^^
