do you think there'll be any clan tournament or any form of organized teamplay server that are going to run on the relaxed realism version?
Yes, there will be. If the majority of players will stick with relaxed mode, most of the tournaments and leagues will use it. RO:Ladder will most likely stay on maximum realism, but if ROHoS is successful enough this time to spawn long term interest to play it on Clanbase and the ESL, I do think that the main leagues there will be in relaxed mode.
And the relaxed mode faces a similar problem likt the hero status: Either it DOES make a pronounced difference, or it doesn't. If it in fact doesn't, why bother implementing it? I for one do think that those indicators alone, be they as subtle as they can be, would alter how the game is played tremendously.
And for the switching over: I have some experience in racing sims, and I can tell you that people who use aids at the beginning are very reluctant to turn them off, as they teach you bad habits you have to unlearn in addition to master the inherent difficulty. Thus I don't really see a large group of people migrating from relaxed to hardcore. In fact, i doubt the number of people doing that will be worth mentioning.
See, realism isn't what RO is about these days anymore. Of course it will be more realistic than CoD (which I actually don't think to be a good benchmark. I'd rather see the original Ghost Recon, the original R6 series, or even RO mentioned here), but the goal isn't to make the most realistic and immersive game out there anymore, but to make a compromise between being realistic and being accessible to Joe Average. And the past has shown us that this compromise isn't easy to achieve. I personally don't know a single title that managed to pull it off. But hats of to TW if they manage to do so.
If they were targeting solely an audience than mainly goes for realism, features like the relaxed mode or hero status wouldn't be in the game. Sadly, I too know that TW can't survive financially if they only cater to this market, thus compromises have to be made.
Still, I am not happy with it.
