If you have more than 300ms, ignore this thread. You're screwed.
As a Brazilian, I always played with high pings in all MMORPGs, some games that I love (global agenda, for example) I can't even play decently. AoC, as a big surprise, was so well-made that even living in Brazil I couldn't feel the ping issues that I found in all mmorpgs before.
Yes, high ping means less fun, but you can still enjoy EVERYTHING AoC has to offer.
The reason i'm making this thread is: 90% of your arguments, eurobros, are invalid. You do not have to predict your enemies movement in order to land a combo. People aren't teleporting 100% of the time, unless they have speedbuff or you're having lag spikes.
2 Classes are bad with High ping: Conq (1-hand) and DT. Sins are still playable because their finisher is so fast that 200ms+ can't hurt you a lot. With conq, if you keep doing the charge thing, you won't have a huge problem either.
So, new players, ignore them and you'll do just fine.
One of my pvp videos with high ping:

What funcom can do to minimize this problem: Put a god dam warning at the character creation screen at the Dark Templar and Conqueror section. You, Funcom, just need to mention that in PvE everything is Okay, but for PvP...
The game experience is worse? Yes. No doubt about that.
Can I still be good at everything? Nothing can stop you there , eurobro, just don't expect becoming a PvP god with DT and Carnage Conq.
THERE'S ABSOLUTLY NO DIFFERENCE IN PVE.
My DT k/d: 5158/2869 <- Not a KDR whore, always trying to win the token. See? it's not the end of the world.
Sorry for my bad english.
