Converting Classes from Pathfinder to FFd20 - Advice?

[Loxsis]

I've played Neverwinter Nights 2, which was built on D&D 3.5e, but I could only use one invocation in conjunction with eldritch blast when I played as a Warlock. The Kineticist can use two infusions with a single blast, one form and one substance, so burn might be necessary, but the effects could be toned down. How about removing the limit on the points of burn they can accept and treating burn damage as normal non-lethal damage (can be reduced and healed)?

I was also considering grafting Kinetic Chirugeon on to the base class so they can do a decent job healing as well. Combined with the above proposal, burn will hopefully be a minor setback.
