@Arsoro86 Et has great Tech multipliers so it gets priority.
For melee attack Tec goes into techniques like Ramegid Type-0 (which is a melee technique) and Photonic furies (which scale off of Tec) so you're not abandoning Melee completely by going Tec. On the other hand goin Mel completely abandons what i just mentioned and goes for single target melee hits only.
Inb4: "but why dont all Techter builds go for Tec then?"
In case of classes like Hunter Photonic furies and Techniques have Worse and Abyssmal Damage multipliers resspectively. On those classes going Mel is the only viable way of improving DPS.
Sorry for the late response.
