We use Eagle for the middle platform at Newties, Newties have a tendency to attack the player as soon as they spawn, and Eagle has a tendency to attack the Newtie and stun it before it can attack you, which lets us hit the Newtie right behind it with greater ease. You have to activate Blizzard manually, so it's far less useful.

But yeah, Frostprey makes Eagle garbage.

If you're just sniping the two newties on the middle platform, you have plenty of range that you don't need Eagle, and Blizzard gives your Strafe a chance for OHKO (11.5% per shot).

Either way, you shouldn't be basing your build now on Big Bang changes. You get a free SP reset so what your skills are now won't have any affect on it at all.
