I always choose bottom tier because I get fixated on why I don't see variety and like to keep the game fresh by playing something new. This means faaaaaaaaaar too often I end up maining bottom tier. I mained Ryu in Vanilla MVC3, Iron fist in UMVC3, Ganondorf for 10 years, and both Green Arrow and BANE in the beginnings of IGAU.
I should have just went with folks more suited to my crossup and strong poke range play style that needs high rewards.
Instead of...
Chun/Ryu/Sentinel in Vanilla MVC3
I should have been playing...
She Hulk/Wolverine/Sentinel in Vanilla MVC3
Instead of...
Taskmaster/Iron Fist/Arthur in UMVC3
I should have been playing...
Wolverine/Nova/Arthur UMVC3
Instead of...
Ganondorf in every Smash EVER
I should have been playing...
Captain Falcon in Melee, Captain Falcon in Brawl, Peach in Project M and Zero Suit Samus in Sm4sh
Instead of...
Bane/Green Arrow in IGAU
I should have been playing...
Aquaman/ Hawkgirl in IGAU
Some of these changes I've made now like Hawkgirl and Peach, but the rest...nothing but regrets. Probably would still enjoy Marvel if I had picked a top tier and stuck with it instead of getting fixated on low tier...and for the record NO Arthur at anchor is not low tier and a joke. Dude is scarier than Dark Phoenix. Block one lance and I can block stun infinite you to death and he has full screen coverage, falls out of combos, and a level 3 instant win. Plus his dagger assist or fire bottle assist at either normal or gold armor variants makes Nova/Wolverine a damned nightmare. Especially Nova...he puts up the barrier and starts popping daggers and javelins and you get screwed.
