So I have played this game on and off since it's release, but I have never actually gotten to 50 because the leveling curve always got boring to me before then. Someone offered to power level one of my characters on a Fire/Fire tank recently and it seemed really fast. This made me want to make a Fire/Fire tank, so I did.
I took myself from 1-26 power leveling myself in about 3 hours. In my attempts to get to 50 before it would take me days to get to 26, so I was sold. I played another day for several hours and have gotten myself up to 41 (Farther than I have ever been before) in just 2 days!!!
I made some mistakes with power/enhancement slots and want to respec when I hit 50 (Which I still need to figure out how to get a respec). I don't know much/anything about Invention Origin Enhancements, so I figure I will start with level 50 Single Origins with a spec to make some influence before worrying about it. I cannot currently install anything so I used an online planner so it didn't have inherent fitness (Or let me put accuracies in burn for some reason), but any feedback would be appreciated, or advice for someone getting their first 50
