Honestly I don't mind letting people buff. I used to bow and stuff but I didn't know the Honor System was a thing until i was invaded by a guy and he literally emptied his Estus in front of me. I caught on pretty quick that he wanted a fair fight. Long story short i fell into this weird glitch where you cant move (It's like a drop near the crabs in crucifixion woods by the bonfire. The guy didn't even attack me cause he could see i was stuck, even when i accidentally got a hit on him. He just dropped an ember and left. I was honestly astounded because i'd never had any experience with online dark souls before this and quite frankly I've never seen behavior like this in other games.
I don't think there are any other games out there with a Honor system like this and it completely contrasts the fair yet brutal nature of the game. I just don't want to see good guys like you and him go bad just to counter the scumbags out there that take advantage of your honorable nature. We'll end up losing the system in favor of two opposing side; Pricks who do what they can to win an unfair fight vs a bunch of Hyper-Capable, previously honorable, guys who'll use their extensive knowledge to just annihilate the opposition for fear of them being the aforementioned pricks.
I quite like the build-up that buffs provide and also the interesting fight and challenge they bring to the battle. For each buff a guy does I get excited because its building up to a battle that looks like its gonna get more difficult.
Anyway, sorry for the long post.
