I'm not so sure. It is true that this app in no way hinders the ability of anyone to continue to play Descent how is or her group prefers. However, it may suggest a new direction for the development of new content for Descent. For example, I assume overlord cards have no place whatsoever in this app. If development shifts to content created primarily for use with Road to Legend, it's conceivable that there will be fewer overlord classes developed. This app need not mean the end of overlord content (the recent release of "Mists of Bilehall" in fact shows a lot of love for the overlord) but it's a legitimate concern.
I think this app looks interesting, and I'm looking forward to its release. I've had the experience recently of playing Descent with someone who generally doesn't enjoy the overlord/hero competition. He dislikes playing as a hero and waiting for everyone else to take their turns, and feels victimized as an overlord. I understand his frustration, but we see Descent very differently, and appreciate different things about it. However, I think he (and others in my group) could really enjoying playing Descent using Road to Legend.
As I've said before, the overlord/hero dynamic is the best part of Descent in my opinion- it's what makes Descent worth playing (for me). This app could be rich, engaging, and fun- but its very reason for existence is to remove the aforementioned dynamic. Therefore, if (a giant, potentially unsubstantiated "if") this app represents Descent's future at the expense of overlord content, that's just unfortunate. If, on the other hand, this app exists alongside "traditional" Descent content, then it's a welcome realm of new possibility.
Thought I´d just drop a like on that post but I think it deserves quoting once more for emphasis. Besides the issue I have with app-technology in board gaming, Zaltyre pretty much summed up my concerns about the direction given by that move from FFG.
Road to Legend really appears to me as being a brand new game, and not a simple variant loosely listed in a floating paragraph at the end of a rules book. There are too many core changes to Descent to justify calling this a variant or game mode. The presence of the app itself confirms that fact. Therefore, FFG have basically put themselves in a situation where they have effectively branched out from the traditional D2E development, so that's a rift by definition in terms of future content. Even if there will certainly be crossovers. But barring all overlord-content from a given Descent expansion is like barring 40% of all content (assuming 40% hero content and 20% for the rest like the tiles and quest mechanisms). It will feed the app with tiles, monsters, and all sorts of things, but half the game is gone. Then sure, taken from the perspective of RtL, new stuff will be added, but that stuff will not be compatible with the traditional game (exploration, monster AI).
It has nothing to do with players' taste. I largely prefer traditional because I find mind-blowing to ever consider removing the OL mechanism, but you may prefer RtL for the full co-op or exploration, or you want to play both then it's all fine and all. But you cannot deny that both "games" will compete with each other in terms of future content, company focus (support, testing, budget), and even the community will be affected.
