Generally, we try to avoid judging people's style of play - as our number rule state “Play how you like as long as you don’t impair the roleplay experience of others.” However, the problem is that it actually had come to a point where it did impair the roleplay experience of others. Yes, acknowledged, it is a move toward less video game, but that in the name of promoting a roleplaying game that was otherwise suffering. Not considering childhood-diseases of the system, there is of course pros and cons with it as much as with most other systems. On the bad side, it puts a limitation on playing and it makes it at times harder, demanding much more patience, more time in general to achieve the same. On the positive side, it helps the spawn levels, it provides an additional roleplay element by portraying exhaustion and it paces down things, allowing people to roleplay their characters without worrying as much about keeping up or have their adventuring party robbed of their adventure by a fast pace loving player.
To judge whether the good outdo the bad, what speaks in favour of the system is that the majority of the pros falls upon the roleplaying game side. If it can ultimately turn out to be an asset to that aspect, I feel it's still worth pursuing.
