Should i upgrade my Isida to M1 or buy something else because i kinds like healing it gets alot of ex which ranks you up which gives you rank crystals

Why cant there be gun discounts because what id say is that M3, M2, and M1 are way over priced Instead of Tank discounts there should be Gun discounts since most ppl need better WEAPONS not better TANKs also some crystal questions How ofton do we get crystals as Daily Bonus? and a suggustion is that we should be able to choose eather to get crystals or Items because you can just buy teh Items with Crystals And what is a "gold box" and how often dose it fall I will post more if i haveb any other questions :)
