Go 7.1. It does very well at this cap with Fire maxed.Shouldnt be that bad in 90 cap either.
In any case, if you are planning to go high level, go Pure INT till a certain point and then add the STR at once. Like if you are gonna go 7.1, be Pure till 70 and add the 10 STR points after that.
Faster leveling that way.
