War is HIGHLY valued now, but must be skilled & have WS quested.
Abyssea levels go so fast, Gear selection kinda moot 75-90... I think most just pick up Pearl set when going to Aby Exp @ 75. Its a good melee set with worthwhile set bonus & you can just macro in WS pieces.
Its a good idea maybe to start Trial GA, Fire path or several others are useful til you can get Empyrean or Widowmaker drop (Vermeil is acceptable to tide you over & is easy to get).
Pld is not used near as much by many, but still has good utility (& still over-laps much of War gear). Pld allows me to solo stuff I cant on BLM for drops also, so its nice to have both.
Your main goals at start will be : Getting stones built up for Aby--- Getting Cruor for Aby needs--- jumping in on shouts for zone boss & Caturae wins to equip Atma & getting good Atma (atma FAR outweigh any weak gear slots)
Once your War gets decked out, you'll be asked not to kill stuff so fast ! lol
(another main goal is to befriend a career WHM & find good LS)
