I've always wanted a Tier X but I've never been able to get one. Now, I've created a reroll to get a Tier X no matter what, with 0 variations in tech tree or tank line. The Tier X I'm targetting for this reroll? The IS-7. So my question is, assuming I have 0 premium time, am unable to play and win every game (stuff happens) and I am nowhere near unicum (allows me to earn a few extra credits because this game does still reward skills with slightly extra battle payout), how long or how many battles will it take for me to get to tier X?
Also, please no opinions on tier X choice or anything like that, I just want an estimation as to the length of time it'll take.
