Nothing to do with low tiers. I play at times when there are less players on and the MM constantly matches me with ranks 7-10.
@LegendaryE agreed. Reim definitely benefits more from the pure cp, I just like AS for the dmg + sustain honestly. I find sustaining his health more important than gaining massive fortified health since every attack gives you fortified health anyway, but I definitely agree AS is more of a niche item not useful for anyone who is utilizing ratios properly, more for base damage heroes. And definitely agree reim is mid game. I can see glass cannon reim being good due to his playstyle but that relying on your team instead of being able to solo play part…terrifies me in Vainglory.
