It was a friggin blast... ToA introduced the whole elemental resists, where you had a penalty against Fire, etc. Pretty sad that in one week's time, I went from terrorizing squishies, to them standing there laughing while they nuked me into oblivion. Frontiers was just a badly implemented cool idea, but ToA made RvR ludicrous for LA's.
God it would have been fun to go back and play a pre-nerf Bezerker or Shadowblade...In my opinion TOA made the game more of a time sink, which certainly sucked, but didn't kill what RvR/PvP was. New Frontiers was the real deathblow.
Man I miss those days. It was exciting sneaking in and trying to off the glass cannons, then jumping the wall trying to get out before his friends made you a meat pudding
