wow has the little built in internet ping bar that turns from green to red or whatnot but it seems generally ineffective in real time. a mod that could detect internet connectivity degradation closer to real time might help prevent deaths by d/c. it would not help for sudden drops when in the middle of a fight, but if there was a sign your connection was fading it may prevent you from engaging in a fight under less than ideal conditions.
generally speaking, if i can see other player characters moving normally my internet is good. i get paranoid about d/c’s when i can’t either see other players moving or mobs are slow in respawning. so far, it would seem, that when in doubt if i go to the game menu and attempt to log out and it proceeds immediately my connection is likely good. if not, i have dropped but don’t know it. i have had a problem in the past when my connection is basically gone but i am still getting game chat although my character is frozen. if i try to log out and it doesn’t immediately go to the countdown, i tab out and get to task manager and close the program.
just wondering if people have other tips to prevent d/c deaths.
