Gangpalnk Rework too much?

After watching Huni play Gangplank after his rework and go on to pretty much one shot a tanky Olaf i feel like he needs something to balance him. Gangplank used to have a really weak early game, barring harass with his q, and picked up this slack with his mid to late game with a trinity or maybe a static shiv.

Now with these barrels and ignite passive he all of a sudden becomes nearly a bigger lane bully than gnar early. The reason for this is his barrels. They simply do to much damage early and he can activate them with his parrley and considering most top laners are melee it isnt an option to take them out before he can explode them. So in effect he simply puts a barrel over the minions and to farm you will need to take harass. This problem consists even when trying to farm under turret. Then we have the issue of his escapes with the barrels. Pre-rework he had nothing but his oranges to help escape. Now he sticks a barrel down which speeds him up and slows you down.

Then is the core reason behind what i feel has made him too strong now. His barrels crit. The problem is that its a full crit. This makes farming impossible for melee range top laners as the damage taken if the gp has crit runes is just insane. But that isnt the issue. The main issue is in team fights. It crits in an AOE and can chain them to chink down an entire team; Couple this with the barrels passive of ignoring 60% OF AN ENEMIES ARMOR! and champs taker EXTRA damage up to 200 extra damage? couple his barrels with his passive and he becomes a monster in every aspect of the game. Be it early, mid or late game.

I think perhaps his barrels are far too strong with no weaknesses, especially considering every gangplank starts flask -_-

Bear in mind this is an opinion and you may have others, reply with yours?
