Here are some comments I have heard around the forums:1. Aegon is only useful at sig 2002. He is only useful for AOL/LOL3. He isn't even that good anymore4. He is only useful duped (probably the only one I agree with. He technically still has uses but starting every fight at 0 combo is just mind-numbingly slow)Here are my thoughts/experiences:1. I took him straight to R5 sig 200, because I took forever to finally pull him. In LOL/AOL content he is almost no different between the different sig levels. With fights lasting 200-300 hits, the ramp up difference is negligible. In shorter content you cannot take as much advantage as with higher sig, but he still can do a lot. I would dump sigs into him because they are very nice to have, but not entirely necessary. 2. Maybe to some people. Personally, He was my most used champ in Act 6.3-4 completion, I have used him often throughout Act 7, I have used him in Cav EQ, and even a number of side events. He is a great boss killer, and unless the nodes are ridiculous (even then , he has a lot of utility) then you can often use him as a main path clearer. The only place I have not used him often is lower content and Variants because they usually are super category-restrictive and he doesn't fit into a lot of groups. 3. He may not be flashy and new but his damage and utility are still top of the line. 4. Pretty much. My advice specific to you: Do it. You don't have to rush it, but he can put in a ton of work for you. Sure, rank up other champs too, but he should at least be prominent n consideration. Put sigs if you can. Make sure you know his combo levels and what they mean. Often, after one fight in Act 6.3+ content, he can be at around 60-80 combo if not more. That opens up a lot of his utility. He is great with suicides, just don't spam sp1. If no suicides, then spam the sp1. If you don't care about health and just want to nuke down a boss, learn the heavy-into-a-sp2 method. If you're not the best at keeping a combo, he has a synergy for that, or use the Nick-Quake evade synergy.
