Already we know how useless 1* & 2* can be (ok, not for those new to the game)...
But now, with new Training that can get us 3* cards...
It makes the 1* kinda useless...
For me, my favourite training is 26-5... There's a chance for 2* Yakov and 3* Catoplebas. I like Cato as monster. It's tough! And drop rates aren't that bad... Easily i can get 1 every 600 TP or so. not to forget the 2* Yakov in between...
Is it any wonder why we need to have a new type of 'premium ticket' and call it 4*+? very soon...
There's also the soon to be released 7*...
I know sometimes power creep is inevitable... but it can sometimes be avoided or delayer via --- new mechanics, new skills, new event requirements (that gives old cards some extra value), etc...
BTW, i still keep a maxed Jane. she's still useful when attacking players... she can be on the back row and still reach the defenders.
