Totally sucks , locked camera = ruined gameplay, dissapointed too much.....Can we lock the camera position near Geralt's back and disable zooming out while combat?
No.
As far as I can tell after watching Jesse Cox' video on youtube places of power give you an extra skill-point to invest, so I guess you'll lose those skillpoints when resetting your skilltrees completly, leaving you only Level-Up-Skillpoints earned to directly place back into a new skilltree. Places of Power also seem to give other bonuses (or where did that igni-bonus come from in Jesse Cox' video?). So it might just get rid of those time-limited bonuses when resetting.I mean come on that makes no sense at all!!
If this would be the case it would indicate there ARE skills which are PERMANENTLY active and you can NOT switch out, because obviously he asked if you could reset skills at at a point and Damien said "yes, but you loose the benefits you gained from places of power". It would make no sense if you could switch "builds" all the time that you loose the stuff from places of power every time you switch, that would discourage the experimentation with "builds", but they want you to experiment with them.
So my conclusions would be that there are active and passive skills. Active ones are the "builds" which can be switched around and have different effects while passive ones are the more "permanent" (probably stat-influencing) skills.
If that is NOT the case then I have no idea how this is supposed to work...
