In my opinion, it would be great if they had a respec feature where you paid per skill/attribute point removed. Instead of adding a point to each stat or skill, you remove it. Then, you simply do whatever you want with it... convert an attribute to 2 skill, or vice versa, or simply reassign them to a different skill or attribute. For example with my build I currently have some shield skill, but at a super high level I would ideally wish to convert that and a couple points of ironflesh into more attribute points, and thus more athletics or WM. I would have to remove a total of 5-6 skill points, I believe. If it cost maybe 100k per skill and 200k per attribute point you wish to reassign, respeccing would actually be feasible for minor build tweaks. However, if you want to go from being a level 36 cav to a level 36 foot-based archer, well... that might be a bit more costly, as it rightfully should, in my opinion. Converting my 4 shield and 2 ironflesh into more agility, and thus athletics and/or WM is a relatively minor tweak, and would cost 6-700k, which is pretty reasonable, I would argue. This method would also really help anyone who has ever fucked up a build by clicking + in the wrong skill or attribute. I just recently ruined my planned 21-15 build by not really paying attention and hitting + in front of the agility when I already had 15. I realized my mistake within the hour, and really could have used either an undo button or a mini 1-point respec... now I'm just gonna stick with this build until I retire, since respeccing isn't really worth it at level 30.
To those of you saying that 6-700k isn't expensive enough to be a good gold sink, you should take a course in economics sometime. It is all about supply and demand. Currently, since demand is so high, and yet the supply is very small, it sells for a large amount once per week, which makes sense. However, if the quantity were increased, the price would then be lowered automatically. You might think that the lowering of the price is a bad thing, yet it is quite the opposite. Lower price allows for more buyers who were turned off before from the absurdly large pricetag. If you have 1 person losing 3.5 million per week, then the economy loses 3.5 million per week. But what if this was changed so that there are 15 people losing 400k per week? This would result in a loss of 6 million per week, nearly double what was being lost before. As I said before my relatively minor respec would cost me 600k at least, so odds are most people would be spending over 400k when respeccing. Now you might say that this might look good on paper, but it will only hold up for the short term, since once everyone gets the respec they want they will stop respeccing and then there is no gold sink left. Once more, not true.
With the reduced price people will respec more often as they wish to tweak their build to keep the game from getting stale. Currently if someone dislikes their high level build and they don't have nearly 4 million gold lying around, they can either respec and lose half of all their hard work, or they can retire, and be stuck as a weak peasant for a long while. Instead with the "pay what you want" styled respecs, people buy them much more often, and continually be able to tweak their build. Not only does this make for a larger gold sink, but it also keeps the game from getting stale for many players, and therefore helps keep the community alive. It's a win-win in my book. Honestly don't see why any of you would be opposed unless you have the "I had to pay 3.5 million so you should to" attitude, in which case grow up.
