Yeah, I just looked at Takumi's stats and skills more and I don't see why he's rated so high on the tier list. Is it only because of Close Counter?He has rather good stats, between his good ATK and SPD he can hit really hard, and if he only receives a Vantage, you better one-shot him or have very hard hitting units / anti-colorless weapons lest he'll take down like 3 of your guys in quick succession before you realize. He's pretty hard to actually kill without that, especially when he gets in your bad range. Faster units to avoid getting double-shot also tend to be flying ones, which make easy target. Then there are tanks who will still take 2 hits before hitting back because they're slower, or high SPD units who tend to have lower DEF, neither will get out unscathed. There aren't a lot of units who hit fast, hard, and don't have a type disadvantage to something. Takumi is in that position, and he only needs Vantage.
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
