if you can't play around it.

I pretty much can't. There is no counter to 3 tile movement, there never has been, and there clearly won't be. Very few units in the game can bait horses out of the box and SI is RNG based for anything else that you might be able to make capable of it. Meanwhile, almost all the resources cavalry teams need are available from GHB or special map rotation.

There's a reason nobody's really agreeing with you.

Probably because everyone on this subreddit runs horses and doesn't want to see them nerfed. And why would they? Easymode is "fun" when you're the one using it.

Also horse emblem on defense isn't nearly as common as you proclaim due to low BST. Maybe your units just aren't that great.

Yeah... that's not how it works, at all. I've seen plenty of horse emblem teams in T20 defense and I'm 100% positive I will in the future. BST is almost entirely irrelevant because it's done in brackets, not 1-1. There's like a 50 BST difference requirement before you stop seeing horses, and that's not possible without whaling merges.

No matter what units I use I can't avoid horses in arena, and I'm forced to use very specific ones in order to counter them. It's not fun, it has never been fun, and there need to be hard counters or nerfs to horses in order to solve the problem. Would you like a picture of my 5*s so you can try to suggest a team for me to use? I'll use 10 sword resets and write down every team I see - I guarantee you horses will show up no matter what you pick, because I've tested it all and had them show up just with even more merges.
