It's highly unclear at this point if you need all 4 of those requirements. From the CS with the Qiqirn it sounded a lot to me like you only need 3 (SCREW 50k alexandrite lol) but it's hard to say at this point one way or the other.
For as dated and inefficient the graphics engine is, the special effects in the game are still top notch. I really liked corsiar's cannon shot, and that red mage's flowery explosion, all were really spectacular looking.
Overall, that is a real motivator for the new weapons and to finish Nyzul and ToAU gear.
There's an irony that a new expansion is what makes people go back to the OLD expansion.
Over all, the WS's look very... elemental. Almost all of them have some sort of elemental afterglow or sort. Hmm, perhaps Level 4 renkeis can now be made?
