So instead of 3 clients I'll have to open an additional, 4th window just so I can freely switch characters and effectively avoid this feature.
Great idea indeed.
Yes you would need multiple clients opened all the time to cheat in combat effectively.
Then at least you would be easier to report, observe and ban for being cheating cheapass.
Big improvement over current situation when you risk absolutely nothing with fast relogs.
There was a cooldown for relog already. up to 10 minutes, so you couldn't just jump between characters in no time.
Yes you could. And if you waited 180 seconds for previous alt to disappear, I guarantee you,
you were
perfectly safe doing it. Sleepiness is different kind of cooldown, it's not meant for
anyone to stop from fast relogging but to participate in PvP with character who just logged in.
Penalty can't be avoided in any way except by having multiple characters logged in all the time.
If it was 2-3 minute combat nerf you would hardly ever notice it if you don't PvP using alts.
