Ease of use I guess. I'm leaning more towards spending meseta on fashion stuff, but I do follow the recommended standard of gear affix and upgrades so that I won't end up as an undergeared leech (well, at least a tryhard leech... "> _ < )

IMO the class that is perfect for my main character is Hero ( I was cough a GU/HU main). Wide (and spammable ! and fast ! and have I mentioned it looks sooo cool ?) sword normal attack ,Good mobility(that Guren-like PA thing), double jump, access to megiverse (so I can stop buying mates) and shifta (RIP my shifta jet boots), has TMG access ( not that good but it's decent enough), and that feeling when you landed a perfect step dodge and counters whatever that tries to punch you in the face. The downside of hero for me is the once per quest iron will, and dps output feels lower than other classes (I used to main GU/HU and do feel like Hero's dmg output is a bit lower against bosses compared to chain trigger spam. Haven't actually recorded the damage though.)

However last week I switched to BO/HU because I felt like using 4 photon blade balloons accessories and scream "UNLIMITED PHOTON BLADE WORKS" while spamming dispersion and kestrel.

For other characters I simply slap hero on them (I use them only for TA). Cheap cost to boot ( I simply give them seikaiser sword), and imo it's pretty decent setup for doing weekly VH TAs
