is this concept so hard to grasp? do you know what pre combat is? do you know what kiting/training is?
No, because you don't have to train/kite if you spam staggers. That time you spent setting up walls and glyphs (which scale like utter trash and do horrible damage) is better spent just SHOOTING A DUAL CAST fireball or incinerate, and doing 2-4x damage STRAIGHT OFF.
You spend setup time to do less damage ->> Dungeons clear slower. Fact, ive tried each method so many times and I realized glyphs were a waste of time at level 40. If you constantly stagger they won't even hit the glpyh or wall, unless you stop dual-casting and use glyph/wall mid chain, which again makes your dps drop considerably. Its silly really.
Also this doesn't adress the problem of sprays and cloaks also absolutely svcking worse than runes/walls.
Anyways, this is all off-topic. Lets just agree that the lower level spells need scaling and master spells need changes, as there is barely any spell variety since you can easily get away with spamming fireball and/or incinerate and doing anything else is
just for novelty and probably will slow down a dungeon clear.
