You didn't have these issues in other mmos because they didn't punish slow movement anything like as vigorously as Titan HM. The only other boss I can think of that timed movement down to the second was Hagan in Naxx, everything else I can think of punished positioning rather than timing. Ps never had that issue in Swtor? I saw all manner of hilarious bridge dives in that pvp arena! Tera was very slick but was also a mature game by the time we saw an NA/EU release. I loathed Aion and Rift so I can't comment there. War was dominated by horrific framerates. Both FFXI and EQ2 were a completely different era of mmo and hence didn't have anything like the pace we see now in Tera/WoW/FFXIV. I'll also add that I played WoW on the US servers both to be with friends from EQ1 and stop myself from getting into raiding seriously (So I went for HWL instead ), whilst I had zero issues in PvE, World PvP and BGs, I struggled massively in Arena due to not being able to pole dance effectively.

Putting the P2P throttling saga in SE's lap is fair enough and yes, they made a mistake with their choice of data centre (driven by bean counters I suspect), but they can't really be held responsible for stuff like Telia's wonky peering.
