It's normal for you to win one-on-one with PA and SPE, but it's not normal to lose.
The weakness of PA is that it is weak in the early stage and will not be empty in the later stage. But your lineup is like this, not in the middle and not in the later. (The output of the steel back should not be charged for more than 10 second at least on the battlefield, which is definitely impossible for the opposing team; Bone method doesn't match your lineup at all (great, it's all physical dps, so few skills); Clockwork will definitely sacrifice itself (SK must grasp it when winding). An SPE that only supports blood and blade armor, you can call you no problem, but your teammates can't. Moreover, it is difficult for several wizards to push the green staff. At the critical moment of silence, if you break your BKB, you will be killed by a kite. And your other teammates 4v 1 SPE may not win.
BKB time is up, let's change. This lineup can only be cut by you and CG. Don't make trouble. Cutting off one will make the battle much easier. Your first choice is also to find SK, sil and lich. The lich can die if he loses too much, but if you can force him to lose badly, you can; Hill won't die, you bastard. He is much better than others. SK, you have to control it anyway. SV can't control his opponent if he gets up late. You first throw one into the abyss, and then find the other. Opening the formation SPE has no output for you. As long as your teammates can avoid SPE and SV, there will still be fights.
