Stumbled across this nice little addon last night – Sapper Enhanced. It announces your saps/blinds/kicks to party/bg/raid/say/etc and also announces when they break (or are resisted). Nice when combined with the messages from Gladius, though this can be a bit spammy.
Before I used this I had a macro setup that would do a “/p blinding %t”, but it was hardly reliable (and annoying to everyone if I was spamming blind while stunned).
Sorry updates have been a little slack the last two weeks, struggling to move house and do everything else at the same time! I’ll be posting strats for dealing with Paladins very shortly though, and also more about the changes to Master Poisoner that have just gone live.
