The only time I have honestly seen the invocation range become an issue is with Vydel. People usually just run away from anyone they see with Charge Mind + High Speed Divine Words up, unless they have a Cat Mask/Rogue... or they're perfectly sure they can tank it just because they pack magic DR stacking. Admittedly, there seems to be little escape from them when you activate Geist Schritt... but I think that one is an entirely different issue made by Boxer, rather than Evoker.

However, I have to agree with Lolzy here - not being able to break the invocation at all is an issue. It makes Devocation be forgotten with ease, so I do think Words of Power should cap at some point.
