Every class including warlocks and ench shamans could do great because of talents.
Actually, warlocks were shit until MoP came out and fixed destro/demo specs. Enhance shamans are shit now because of base resilience. MoP came out with the 40% base resil and indirectly nerfed enhance across the board by 40%. They've gotten a few direct buffs since then, and are still in a shitty place. Enhance doesn't get good until 26 when they get stormstrike, and even then it's still missing a lot without Windfury.
All those talents you are talking about either became baseline as part of a spec or got baked into the abilities they buffed. No reason to have them as separate talents you spend points into anyway (because they are mandatory).
The OP is looking to make a private server and wants feedback on balance. Well, 5.3 (soon to be 5.4) is going to be the best place to start with balance changes, including abilities and talents.
If he goes with a 4.3 patch it's just going to be a cluster fuck of classes that have 1 viable spec because of OP talents and abilities available to that spec.
