MAR/WAR advice

[Claire_Pendragon]

As a MRD you will do less dmg, and generate less threat, which might be the reason you end up using an extra Overpower more than you'd like.

I suggest facepulling with flash, keep running forward, then turn around, and overpower the mobs that were behind you.
This will help save u TP if you use tomahawk. (If TP is an issue, dont use tomahawk, except for situations you must)

If you absolutely must, put 0.5s-1s delay between your WSs at the end of a pull, to help build up some TP for the next pull. (I usually go with a Maim combo, just to have Maim up for the start of the next set of Overpowers.)

Once you are a WAR, you'll do more dmg, and you will be able to use Flash 1.5 more times, before running out of MP, which honestly makes quite a difference.

So yes, use invigorate for now, as you will have other methods to keep yourself going as WAR.

EDIT: You could also use food that grants you a decent amount of VIT, to also add to yoru dmg, which would lessen the number of times you would need to overpower.
Most food is relatively cheap, and a few extra points can help you if you were on the very edge of losing hate before.
