Ddraig mentioned it because the Longinus Smasher was unlocked due to their mutual understanding with Albion. It's stated clearly in the quote you just provided. Wyverns are only connected in regards to them both being unlocked due to an understanding with either Albion or DD's past possessors.

I don't see that as being a technique-type. Precision is something everyone who can control their power should be able to do, but as for why Yubelluna didn't target Ise I can't answer that as I haven't read volume 2 thus far. The most logical assumption would be that after his getting his ass kicked by.. Mira I think it was, she didn't think he was as much of a threat as the other 2 were(which was true at that point in time).

I never said I want Ise to be a master at everything, unless that was just a comment you were making, to which I completely agree. I love the team collaboration in DxD and the fact that everyone in Rias' group is a power-type who is working on gaining some techniques makes them skilled and powerful but not perfect which is really fun.
