though, I'm watching from a far, like, as far as at E1 at the moment..
i do agree that you need the entire "LUCK" you can get to have an R5 squad... Maybe, Mars world is a different story, specially M1, as i notice that you need the entire world red in order to achieve R5 ASAP, hmmm...
i do notice, some colonies, 3 ticker distance before tick 20, enemy units killed 120 already... conquer 2 colonies, unit lost "0" im like hmm??!
very interesting...
either I'm always unlucky if that's the case, or I'm just that noob happily goes lucky and get stuck with R3, i get my R4 on havoc most of the time by the way...
weeeee~~~~
