In actuality, you do need a certain amount of STP to even notice a real difference, much like people who cream themselves over haste will mock people with "only" 10 - 14% haste in gear.

Yet the point stands that when utilized correctly, Store TP shaves hits off getting to 100 TP which then increases weaponskill frequency and thus overall damage.

Ignorance of the benefits is perfectly fine when someone has the open mind to learn from those in the know but it is not fine when someone attempts to pass off ignorance as a virtue.
