Inferno towers

Okay I understand the last updates, the re-positioning of the towers when set to multiple targets was slowed. But what really pisses me off and I don't get is why they are so strong still. I have a fairly maxed out th9 base, and I can try attacking an uneven "rushed" th10 base with low defenses, besides the inferno towers, and lose. I don't get it. I think its a little unfair after putting all this time into the game. I can deal with lvl1 towers sometimes. But even those are a pain sometimes.
