Anyone else fed up being "Stunbot" with the latency issues?

[Anthreas]

So, I've been having issues being the Stunbot Paladin of the group that if I miss ONE single stun I'm cursed out and ridiculed. The fights I'm mainly talking about are Chimera and Ifrit (yes I know once I get past needing these I should be free and clear, but this is where I'm at, at the moment). According to my screen I have NEVER failed to hit stun in time (at least according to my screen). Considering I literally just sit and auto attack waiting for the ability I'm supposed to stun, I do it. But always at clutch moments, my stun, which, according to my screen went off before the cast time even hits half way, fails to block it and tends to wipe the group. I have the fastest Internet available in my area(FIOS) in Los Angeles and i'm on the Excalibur NA (Legacy) server, yet I'm still having these latency issues, not only with stuns but also with just regular avoidance techniques. So I guess my overall query is, does anybody have any suggestions? Or does anybody know if anything is being done about it?

Edit : Funny thing is, is I wouldn't mind the role, if it worked correctly, and i'm now currently resorting to refusing to do it until I'm geared enough to MT and let someone else deal with the pressure and ridicule.
