The removal of TP is just a bad decision all around. One of the biggest shocks, and therefore best learning experiences, for me was while leveling Warrior. Spamming Overpower destroyed my TP bar. First few times I did that I discovered quickly how to better manage my TP and how to better manage threat without relying on lazy methods.

While TP was not a concern in most fights, it still had its place for AOE. Its removal concerns me because I've watched other MMOs start pruning things "because it's rarely used and/or seems unnecessary" and those MMOs aren't doing so well anymore. One of the things I boasted about FFXIV was that the devs didn't succumb to bad decisions like other MMO devs. I'm afraid I can't say that anymore....
