You might cap attack on XP mobs but even Abyssea NMs benefit from the extra attack. Take that outside (where DRK is useful) and RCB crushes Carbonara.
Most of the mobs in abyssea only look like you're not capping attack since they either have level correction and an unknown level or physical damage reduction. The only things outside where that's going to be a really big deal is VW and some Dynamis NMs. Even still, there's arabiatta. Dragon meat is common as hell now, so it's not as big a deal.
Regain is 1tp/tic or every 3 seconds. You average WS round will net you 2-3 tics when buffed 6-7 unbuffed, you'll find yourself at 97-102 tp after your hits, hardly worth gearing for. You also wont have a refresh earring as a mage or a TPbonus earring for your WS sets. Regain earring isnt a good choice spread the word.
Well, if it's going to give you at least 2 ticks, that's all that's needed to make a 5 hit with 44stp, meaning tactical can be dropped. While I am excited at the thought of a new Refresh earring for my BLM, thanks to VW needing some support, Refresh jobs are making a comeback. There's also the proliferation of Refresh gear on top of those jobs' advanced refresh abilities, this means that 1 refresh tick isn't that big a deal since you often have more refresh outside abyssea than inside.
With just a BRD and WHM/RDM, you have 17mp per tick with relatively easy gear to obtain.
Wtf am I going to use TP bonus for? It's pretty useless for Catstrophe or Herculean Slash, which are the only 2 WSes I use.
