Not saying we dont have enough..Just an idea of a small extra thingy that acctually can be good for those who do adv and need to vait 30 min on the slow general to do a block. and i speak for my part when i say its no fun to send in all generals and see after 15 min most are in, but the poor dude i needed for first attack or second attack containing block.. would love to use my star coins on a buff like that.. And to follow up your answer..
We all play different. i dont use star coin for gem or prem as i buy both with prepayed card and have plenty gem and prem time.. so for my part. the weak and ranged and in some times the catapult can be usefull. not much else. thats the general thought behind my idea..
We all need to understand all play different ways so a good idea for me may not be too good for you. but with some tweaks from a dev it may find its way to the game and be usefull for many player.
