What is the end game progression for Tanks supposed to be?

[Nabian]

I have the i90 body, gloves and ring the i100 pants, sword and shield. I think everything else is i70. Is it better to buy up i100 or i90 pieces at this point? Either one requires grinding tomes afterall.

Passed Coil part 1 for the first time last night...so I'm going to see how far I can go into coil. I'd like to get at least to average item lvl 90 before attempting EX Garuda again (so far two tries after watching video).

Make sure you cap your tombstones for soldiery every week. Since myth tombs (although a pain to grind) are limitless. I would purchase soldiery gear as you are available (starting first with your body). Get myth upgrades until your i90.

You have more than enough gear to handle Ex primals as long as you know the mechanics. The hardest part of Garuda Ex (if MT) is learning to time your IB so that you have it available for double wheel (if tanking garuda and suparna *don't recommend*). If tanking chirada and garuda the timing is spaced out a bit and easier to handle. If your the OT it's super easy. Just grab whatever mob the MT doesn't and kill it. Then pull the other sister off and kill it. Grab spiny during tornado and let MT take it when your at 2 stacks. There are a few detailed guides online I would encourage you to check out.

If you can dodge, then your only concern with titan is finding 7 other people who aren't brain dead.

Lastly Ifrit imo is probably the easiest of the three original ex primal fights (although leviathan is a close second).
