There are already two dps-tank jobs, please don't make Paladin the third.

In addition to TP issues, several PLD skills need to be buffed to be more useful in more cases.
1. Tempered Will - Severely limited use cases in a few boss fights. Not sure what buff would be appropriate for it.
2. Divine Veil - Relatively useless outside of raids since it doesn't give you the buff along with the rest of your party. Recommended changes: include self as target for buff, remove outside healing requirement, extend range to 20 y radius, increases enmity, reduce recast time, possibly add another party buff.
3. Cover - Increase the range to 20 y and add another beneficial effect.
4. Shelltron - Add blocking magic damage effect for ~15s; damage blocked is added to enmity.
5. Shield bash - remove combo interruption
6. Shield/sword oaths -> Off global cooldown
7. Clemency - remove combo interruption, uses less mp, and reduce cast time to 1.5-2s.

This would help raise those skills to be used as frequently as WAR uses their relatively well-designed skills.

1. Tempered Will - ... Not sure what buff would be appropriate for it.

It can be reworked and used as TP/MP balancing tool. Transfer 25% of TP into MP and visa versa depending of which is higher. If %TP > %MP then 25% of TP transfers into MP. If %MP > %TP then 25% of MP transfers into TP.

For example PLD have 1000 MP max and 100 TP max.
If during the fight PLD have 750 MP (75%) and 10 TP (10%) then after using [TW] he will have 500MP(50%) and 35 TP (35%). Same for MP=>TP transfer. 200 MP (20%) and 55 TP (55%) after [TW] will became 450 MP (45%) and 30 TP (30%).
Transfer rate may be different.

7. Clemency - ...

IMO, any cast time abilities for tank is silly. Clemency should be instant (or even oGCD instant), but have high potency only if applied to PLD himself. If applied to any other party member potency should be reduced for, let's say, 80%.

3. Cover - Increase the range to 20 y and add another beneficial effect.

I think it was in Ragnarok Online that the "take damage for your ally" skill also transferred the buffs you had to your ally, so in our case Covering for OT or MT could also give them Sentinel, Rampart, Regen or wtv. It would be kinda useless considering you're taking damage for them, but if the effect passed on by Cover had its duration reset it could be...at least more useful than it is now. Just a random thought, though.

All the things 1.0 PLD could do sound so nice, though , why can't the same people re-design the class?
