No, Bioware lost me totally when they revealed they were removing companions and romance, two things that have been in just about every Bioware game to date. Doesn't help that every gameplay video I've seen had rinse-repeat style MMO missions, those get old super fast.
That seems like an oddly specific thing to highlight as the key reason you're not getting a game. Certain mechanics, and features are simply not suited to certain types of games. We shouldn't put developers in a box, and tell them "hey, you've always made this style of game, and done X/Y/Z, so you better keep doing that forever or I won't buy your game." It's totally fine you're not interested in Anthem, but the fact of the matter is that romances and companions wouldn't really add much of anything to the type of experience they're going for here. It would really suck if gamers just started looking at all devs as one trick ponies, and refused to entertain the notion of checking out their games unless they always adhere to very specific things they've done in the past.
How many other third person shooters, loot driven, or co-op centric games, etc. are you looking at and going "well….the main reason I'm not into this is because there's no romances or companions"? Probably not too many, right? Like, whenever Borderlands 3 drops for example, I doubt you're going to be passing on that for those reasons.
Again, it's totally cool if Anthem isn't your cup of tea for a myriad of reasons, but I would really hope that those reasons line up with how you judge the kinds of games it's actually competing against. Because if you're not, then you're part of the reason that most publishers would rather force devs to play it safe, than give them to freedom do something completely different (such as GG completely switching lanes from Killzone to Horizon: Zero Dawn). It's not fair of us to expect somebody to do basically the same thing over and over with a different coat of paint. The message you're sending Bioware shouldn't be, "I'm not buying this game because it doesn't a copy a formula you've followed in the past." It should be "I'm not buying this game, because I don't think it's good enough at what it's actually trying to achieve."
