Considering the two games are in the same genre and are competitors, I would think it interesting to maybe produce a crossover between one of these two games.
Of course, anything talking about Dota or HoN is always controversial on these forums.

Well.

FOR THE LEEEEEEGION!!!

I wouldn't.

Everyone is entitled to their own opinion so if you wanna... JUST DO IT!

**** the police.

Well I know for a fact there is a LoL and HoN Crossover. Angry Goran video.

Just gonna leave this link here if you want to watch his series
I believe it's near EP 6 or somewhere around there, haven't watched it for a long time, so idk. That being said it might be a LoL and Dota crossover.

Hey sounds like it could be interesting why not give it a shot

Yeah, I know what you mean. Just wanted to throw that video out there. But it would be kinda funny.
A scene in that story could be where champs from Dota/HoN are just having a regular match and the LoL champs are having a regular match then there's a magical rift making half of a Summoners Rift switching with half of a Dota/HoN map and the LoL champs just going like "What the heck happened"
