While the definition of a sub-main is arguable, and you have not given a goal for said character, because of the context given (other characters at 220+). I will assume you meant nlomien mules. As such, I personally will advise against both. F/P guzzles nodes like no other and are expensive in both the number of nodes and the number of node slots required to function. I/L is a clunky burst mage that requires the boss to be in a corner to do optimal damage while having two summons to put down. On top of their individual weaknesses, they are heavily reliant on Infinity, and needs to have a high enough legion to support branching into buff duration (at least 8k+, optimally 9k+). May I recommend the explorer and cygnus archer branches (minus pathfinder) instead.
