Well since you are removing Haze Bomb from the 1* line and moving it to a 2* line, then why even have a 1* line? Any and all weapons/armor that can reach 5* level start as 2*. Why not shift all current weapons/armor down one star level and adjust cost as well. Thus the following:
1* - 50 CE - 400 CR
2* - 200 CE - 1000 CR
3* - 400 CE - 2500 CR
4* - 800 CE - 5000 CR
All 1* items stays as 1* and everything else will move. Of course you'd have to change requirement to gain access to T2 and T3 but that is a minor change as well. And later when you release the core you can release a full score of 5* weapons for our upgrading pleasure.
do ya mean for example for 1* 50 CE AND 400 CR ? i mean OOO will never make crafting for CR only cuz noone will buy energy so no profit for OOO ... I dont get your idea kinda >.<
