I quite disagree.

It is possible complete content with 240ms lag, but the content is harsher. For instance, you have less than a half second to avoid AOE that normally are giving 2 seconds for a player with a ping less than 100ms. It is quite common the client shows the char exiting the bad before the cast ends but taking the damage anyways.

I know that because South America is one of those places with 240ms+ lag. And I had to time better my movements to not get caught by mechanics.

Do you think you are exaggerating a bit? You think that playing at 240ms gives you 1.5 seconds lag over someone at 100ms? I've done O4S at 240ms (I'm from Australia on NA svr) - never once did I feel like I was disadvantaged due to my ping. I've also done Susan/Lak at both 140 (Tonberry) and 240ms ping - both felt the same.
