100% pay to win.
If you have no problem with that you will be fine.
Regularly buy what they beg you to buy and you will do fine.
Balance changes constantly.
Also constantly new mechs...
So, no stability and never an end on paying...
Same like WOW, as most players reached max-level the developers simply increased this max-level and everybody has to start over again...
Many people have no problem with that.
For me personally a complete NoGo as it completely negates all achievements one has....
