Oh god you saw the Cass Mod hatefest of today ?
Ugh, yeah, I heard about it. And immediately downloaded it to support the modder.
I just don't see the big deal. It's a MOD, it's NOT infringing on canon. You'd have to be delusional to believe your mod was canon.
I chose PC specifically so I could mod. Mods extends game longevity - look at how long Skyrim has stuck around because user-created content is such a huge part of the community. Just make a note of whether or not the mod is lore-friendly or not. That's... all. Different people play for different reasons. Insisting that a game can only be played one way, when it's made specifically for users to roleplay, self-insert, etc. is contradictory.
Also - there is now a Solas romances EVERYONE mod. Just like there were bisexual Alistair and Morrigan mods. It's cool. It's a mod. Don't like it? Don't download it. If you do like it, click that "get it get it" button so hard your mouse breaks.
No one forces ANYONE to download a mod. Or to accept their head canon as the sole only acceptable truth. That's the Qun y'all.
