All of us who contemplated cancelling our accounts because our raid group couldnt zone in because some teleport bot in DM was checking dusky tomes 40x/hour
It pops up once in a while now, where servers are busy, so ANY more unnecessary strain is bad, keep in mind, we have the random dungeon and raid finders now, which have generated a ton more legitimate instances, the 5x/hour that's in place for solo and non random content is a safeguard that these 1000's of new instances aren't bogging the servers down enough to completely inconvenience players. You having to do a run every 12 mins is better than a 25 man raid of players quitting the game.
At least someone remembers why they put the limit in there in the first place. Stupid hunter bots farming tomes/gordok tribute chest.
But it is rather silly that they refuse to at least extend the lockout rule. I've had several instances where my whole raid has been locked out for an hour over hasty raid lockout resets due to conflicting IDs.
Then again, if they push more guilds to 25 man, then they will have more instances available...
