arena enemy frames

is there a addon that automatically detects the enemy once the match begins?

i have the gladdy addon and you have to target the enemy for it to register, which sucks.

any addon like how gladius works?

also anyone else having the issue of stealth classes being greyed out of the frames??

cant even click them, have to manually click their body every time

There are no arena units in wrath. No addon can work like Gladius, unless the Warmane administration makes it so (but it's "not blizzlike").
Plenty of threads on the forums here explain why stealthers grey out (again, limitations of TBC, can't be fixed unless administration cares).

If you use the correct version of Gladdy, it will find enemies you've seen once before as soon as the gates open. That's about as good as it gets.
