1: not really just by virtue of him sticking to Urien. If you're going to say that Laura is cheap, Cammy is cheap, etc and NOT acknowledge that Urien is also cheap than you're an idiot.
2: sadly never. Not my thing. Maybe one day if just to fuck around in Vegas.
The Aegis is a very, very stupid V-Trigger. It's probably in the top 3 or top 5 best V-Triggers in the game. It, like other re-tar-ded- V-Triggers, can entirely change the outcome of a match. Urien can just throw out his shoulder charge, cancel into Aegis and (1) if the guy blocks it that gives Urien a 50/50 that you have to respect or (2) if it hits he gets about 25-40% damage or more. Not to mention his Shoulder Charge and the Knee Drop are essentially free ways in and can't really be punished on block and in the case of the Knee Drop is a real pain in the ass to anti-air. Not to mention that Urien can do Aegis on his wakeup and if you dared to press a button you might get a hit on him but the Aegis will hit you and let him get his shit started. The only way to hit him out of that is to use a Super or do a regular throw BUT Urien can also do wakeup EX Headbutt which has invincibility.
The instant Urien has Aegis at his disposal is a very bad situation. But like I said, a lot of characters have stupid V-Triggers. Ibuki, for example, can use her V-Trigger 1 (the bomb one), get in, cancel into her V-Trigger, and you're instantly in a 50/50 situation where you have to guess. And guess what? If you guessed wrong or right she gets to go for another 50/50 because she has two bombs.
Abigail is equally dumb:

Basically if you make one mistake against this character he's going to do 50% and get you very close to stun or he outright stuns you.
Street Fighter V is a bad game. In case anyone's wondering "Well, why do people still play it?" It's because Capcom dumps money into the tournament scene and has a deal with E-Sports organizations. Attendance for V has massively dropped in comparison to attendance for Street Fighter 4 but people show up at tournaments for a chance at that prize money.
It's the same exact reason why Injustice 2 is still limping along in tournaments.
