*shoves paladins to the side and boldly steps forth*
Ahem. Common practice for leveling WARs / new players who are leveling WAR is as follows for pulls involving multiple mobs:
1. Tomahawk.
2. Overpower.
3. Overpower.
4. Start Butcher's Block combo.
5. If necessary, weave Flashes between weaponskills.
6. If Flashes prove insufficient, insert as many Overpowers as you deem necessary inbetween your combos.
7. If you're in real danger of losing multiple mobs, break your weapon combo in order to Overpower.
8. Remember that Skull Sunder and Butcher's Block have better single-target returns on enmity than Overpower.
After each pull, reassess your need for snap aggro based on how quickly or slowly your DDs were pulling off you, and then adjust how often you Overpower and Flash accordingly. You'll need more if you're significantly outgeared and/or a DRG/BRD/BLM is getting lucky with crits or procs. You can settle for less if you outgear your DPS and/or your DPS consists primarily of single-target DDs. These are general guidelines, not rules: if on a particular pull you feel you need to adjust in a certain direction, DO SO.
Do keep in mind that Overpower and Flash are both tools, not crutches. Don't mindlessly spam Overpower, and strictly speaking Flash isn't necessary (in fact, later on you'll want to swap it out in some endgame instances for different CDs) though it has its uses (snaps aggro on mobs behind you and to the side, doesn't wake slept mobs, can be used at any time without breaking weaponskill combos). Also keep in mind that, owing to its nature as a weaponskill, Overpower scales better with level and gear compared to Flash.
I personally prefer to save my MP so that I can Flash after Berserk runs out, since the large majority of healers are either incapable of or don't bother with cleansing the four-second Pacification (and SCHs don't get Leeches until level 40 anyway).
Tips to help manage your TP better:
1. Use Wrath-reliant weaponskills (Infuriate and Steel Cyclone) whenever possible. They are TP-free weaponskills, so the sooner you use them the more often you're saving yourself from using some TP AND giving yourself time to recover TP. You can only use them once you hit 5 Wrath stacks, which are built through combo'd SS, combo'd BB, combo'd Maim, combo'd SP/SE, Berserk, Vengeance, and Infuriate.
In your case Gegenji, since you're only level 37 and don't have Steel Cyclone yet (a big help with AoE enmity), you should be using Inner Beast whenever you can unless there's a big hit you need to mitigate, in which case hang on to your stacks and time your IB.
2. Substitute Flash (and Steel Cyclone once you have it) for Overpower every once in a while. Â
3. Refrain from using Tomahawk unless it's for initiating a pull (standard practice) or following up a Provoke attempt to peel an errant mob off a DD/healer back onto yourself from range. Combo'd Butcher's Block peels better for less TP. Yes, you'll have to give up on all the hard work and effort that went into arranging the other mobs in the perfect positions, but walk on over there and BB that sucker anyway.
