Q:
Ascended & Runes/Sigils?
You forgot one more option
E. There will be only a few variations with runes that Anet feel are worth preserving. All the rest will go the way of the dodo (and the stat combinations that are already missing from ascended)
But more seriously, the most likely option is A. Apparently we didn’t get it right away only because they had a bit of a problem with implementing it, so it’s likely that once it’s solved all ascended eq will be converted into two-slot version, with ascended upgrades accessible.
Remember, remember, 15th of November
IMO I think the best route is normal ascended armor with a regular slot for sigils/runes. Then allow for the option to mystic forge your ascended eat into an infused edition for 5 AR on the armor/weapon. If you think about it, 6 armor pieces infused would already give +30AR which is nearly double current AR cap. On weapons, infusions will be 10 AR on 2handed and 5pm single. This means with full ascended I hope to get around 100 AR. 30 armor60 accessories+10 weapon(s).
