Me think it is a bit too early to start establish a melding plan on i150 craft accs.

1. There might be new patches incoming introducing (maybe) higher than ilvl150 crafted accs, making the actuals i150 not opti

2. We don't know the Acc caps on savage Alexander

3. We don't have a decent access to gradeV materias, I think actually the only way to get them is this Mutamix dude, and then again melding gradeIV is gonna lead to a non-opti meld plan.

4. It seems like going all str is ok for every content released

On the other side, atm I think a full pentamelded i150 craft accs set is the best u can have for a tank. But for how much time ?

So, I just bought an i180 slaying set and an i180 fending set, I'm going for i190 slaying from Alexander and wait for future content/patch before starting the crafted accs madness.
