Now, since the design philosophy on talent trees has changed for Cataclysm, instead of having a max build with no talents to play around with, you have a build with a few talents that can be used for SITUATIONAL gains.
Since these gains are very situational, wouldn't it make sense to be able to easily change them? Otherwise, you can't make use of those situational talent points as easily, and their purpose becomes rather void.
That is why he argues that it should be easier to change the talent points without having to go to a trainer for a complete respec. However, since he still wants dual-spec to be relevant, he suggests that you should still be locked within your chosen tree.
