I rather enjoy the new Gangplank. Yes, down-vote me for having a dissenting opinion, but I'll keep my combativeness to a minimal.
1.) You have taken away his ability as a hit and run champ, he no longer has any mobility and cannot escape when he needs to as he is to squishy to engage in combat unless fully built as a tank, which is a lame and boring play style for him.
I think his new innate encourages hit-and-run. I played the old Gangplank, but I cannot recall ever wanting to dash right in, get a nick in, then fall back with him. I've adopted that mindset for new Gangplank, though.
2.) Please roll back E, E is beyond terrible. You can feel free to delete E off my account, as I don't need it.
I always eyed his old E as... odd. It wasn't anything particularly exciting; just a stat boost. Old Gangplank's primary damage output lied in his Q and R alone, so either he was doing a crap ton of damage or was just auto-attacking. He relied heavily on items to make him formidable outside of his Q and R. As for new Gangplank, I feel good when I detonate a lot of barrels; I can push back encroaching waves and join the teamfights, I can feel I'm contributing more if I chunk the enemy tanks with my barrels. It just feels good. But if you preferred the old E, nothing wrong with that.
3.) The serpent thing is stupid, if GP falls behind there is no way he'll get to the retarded 500 count. I've never got 500 in a game so far, even attempting to farm with the barrels. PLEASE BRING BACK THE OLD E!!!!!
I don't want to diss on you, I haven't seen you play, so I'm in no position to judge your skill, but garnering Silver Serpents isn't totally impossible. It really depends on the match-up and how the laning phase goes. If it's a relatively passive lane, you'll have a much easier time getting your serpents. If you have a rough start or just a poor match-up, yes, it's hard to upgrade your R. I found once you get into the lane game, your serpent income should rise exponentially since you'll have plenty of barrels that deal tons of damage.
4.) Texture update i can't complain about, however his voice is just plain old wanna be pirate. Old gangplank voice was funny and matched his personality, now it seems like a cosplay pirate gone wrong, where is your quality control?
Well, of course his old voice matched his personality; it sort of was his personality. But if we're talking about story, he was described as straight up brutal. That wouldn't rule out him being "jolly" of course, but I wouldn't have been able to infer that from his old lore if I hadn't heard his old voice over too.
5.) Gangplank was my absolute best character, sense the rework not only is gangplank no fun to play anymore, he is also now my WORST hero to play with. From #1 to WORST, thanks for ruining my game experience. I'll never play gangplank again.
If that's how you feel about him now, I can't dissuade you. To each man his own.
