Ah, the infamous CTM (click-to-move)... it screams of real-time to me. I understand the wrist and finger breaking concerns, and the lazy-gamers who don't want to manually direct their characters. I just don't feel that it fits in well with Eschalon's gameplay.
With Spiderweb games, you have a system that "enters" and "exits" combat mode... Eschalon doesn't really differentiate (other than playing some battle music when you start swinging). I've played the Avernum 6 (and 5?) demos, and the CTM feels very unnatural in an entirely turn-based environment. It's almost as though the turn-based nature of the game is interrupting the CTM functionality, and the lack of character animation in Avernum really makes it stand out.
It works really well in a game like Fallout, where regular gameplay is in realtime, and only the combat aspect is turn-based. It's also good in Heroes of Might and Magic (which is entirely turn-based), where you have to click once to set the path, and again to execute that path. Of course, HOMM is half RPG, half Strategy (or more like 25% RPG and 75% Strategy)... so it's a bit of a different beast.
In Eschalon, I think the combination of auto-walk, quick travel, and portal options more than makes up for the lack of CTM. In fact, it would be one of those options I would only agree to if it was optional... it might even be a deal breaker if it was included without the ability to disable.
The 'official' challenges -- these challenges were originally forum-based and were done for our own amusement... putting them in the game is not just pointless but distracting, if there's no significant and obvious as-you-play XP gain from it . . . the beta-testers say there's an XP gain... it's not actually apparent, though. I say get rid of it, since I don't see how it makes the game better, and BW doesn't have to waste any coding time on improving it in terms of balancing.
...Others probably disagree, though.
Are you referring to the optional rules or the titles you get for completing certain feats? If the latter, I'd be pretty much in agreement, but you don't get any extra XP from those... the extra XP comes when you enable all 4 of the rules (aka Hardcore Mode)... it's really only enough to maybe get you an extra level by the end of the game.
The optional rules I don't mind, but I'd like to see a bit more... customizability in terms of difficulty. Ideally I'd have a hybrid difficulty + rules mode... I've been working on a matrix... maybe I'll share it with everyone, or maybe I'll just send it to BW instead.
But the titles I would definitely vote out... as a matter of fact, it's going on the list!!
