Maybe I'm too quick to judge as I haven't finished the game yet, but so far I have killed around 10 to 15 bosses, the sentinel trio killed me 3 times, executioner's chariot, pursuer and lost sinner killed me once, half scorpion woman (or half woman sccorpion) came really close, and every other boss just barely touched me before they died (a couple of them didin't even touch me at all); on top of it I was deliberately keeping my soul levels low (I have around 100K unused souls and bought lots of stuff from merchants), my character is pure melee with a +9 Claymore and I didn't summon any phantoms.
The game is by no means walk in the park, but out of my 50 something death so far I only died 6 times to bosses, which is dissapointing since I always loved boss fights in Souls games and almost every boss in Demons Souls and Dark Souls had kicked my ass during the first playthrough, maybe I'm just better at it after sinking so many hours in previous games, but so far the bosses really aren't as challenging as I expected, anyone else feel the same way?
Are there any real hard bosses in the game like Smough & Ornstein that could make me eat my words ? Or should I just join the Company of Champions convenent? I am looking forward to NG+ because I have heard that it is really hard and different this time, but right now this stuff is weak.
