Ilvl110 probubly.
115 no chance. Unless they bump high allgan to 120.
No and no. It looks very much like 115. It makes sense that it'll be the same deal as the Animus upgrade (i.e. ilvl gets raised first and then you work on filling out the stats). So for all intents and purposes, it will be quite some time before the "i115" Novus will be on par with High Allagan. It seems like they want this to be the case for 2.3. Then we should see the next episode of coil provide weapons that are better than Novus, then we will have the next Relic upgrade path opened up, rinse and repeat until the end of days...

I know it hurts some people's brains to imagine that High Allagan will only have a few months alone at the top of the tree, but I fail to see why it should persist as the top tier weapon when people will have had to have put a metric craptonne of work into their Animus weapons. It doesn't seem like the next quest line is going to be any more sensible than Atma/Animus, and there should be proper rewards for content that is, at the very least on par with time taken when compared to Wave weapons and Gerolt's. If I'm an example to go by I spent way more time getting my Atma weapon than I took to get my Wave Axe (1/20). Yet it's going to lag behind until I've done another metric craptonne of work.
