Being able to see party member's TP would be nice, even if it was just a number rather than a gauge. "Communication is better", someone will respond, but it takes unnecessary time and effort (especially with a cross-regional party who may not all speak the same language) and is difficult to do when using something besides a keyboard for control. That's just a pet peeve I've had since FFXI.

To add to your lot idea, some kind of Need before Greed system to keep people who are just being greedy from ninja-ing loot from people who can really use it.
