it's actually good for those who're not stuck at max lvl like me.
imagine in 6months (if you're still playing) you send 3* and you get 8* six month/season later.
if you guys promote every season that's like an increase of 5*+6(months)=11stars or 11star convert to percentage, x20%= 220%.
too bad they increase all of the skills and not only the white skills.
and it also cost money which i will never use.
if it's free i will gladly use it. this is where u wrong eastsider
the best way to use this is to send 3* 18yo. it's a waste if you send the high star. so when u get it it will automatically be 8* doesnt matter if the 1 you send is slow trainer because they say guaranteed 8*, and sometimes the slow trainer are actually good performing player during matches compared to fastrainer
