Am I missing something? All I read here is not something I know as 'solo-tank' strat, it's just the proper strat.

Since week 1 it's done this way.
It mirrors the pattern of old A1s impact AoEs, one most far away on x-axis, one far away on the y-axis on opposite side cornerwise.

Probably another non-optimal savage strategy distributed by Mizzteq? Yes, it is.
Pretty much like the "swap after 2 stacks" desaster we had with O2s.. a swap after the actual tankbuster is waaaaay smoother. Mizzteq, stop teaching people stupid strats.
