I think Pendles is in a reasonable state so far but he has twisted the metagame out of shape like Alani did initially. The most frustrating games I’ve been playing are opposing teams with Pendles, Deande and a third fast melee like Caldarius or El Dragon. They just appear out of nowhere and just delete one player after another. Unless your team is massively tanky they just roll in and crush people.
However, tackling Pendles individually is a lot more bearable. I’ve had quite some luck with the following characters:
Ambra: I keep Sunpots up as much as I can and keep my heat bar filled. If he drops in on you, smash your staff into his face several times and then health drain him. I’ve stopped using Radiant Halberd to take the fight to the other team in exchange for the Flame Staff lifesteal to defend myelf and my team.
Attikus: I had a game where I needed to take a break from healing so I picked someone bulky. I went full lifesteal for Attikus and crushed the snake flat. it was Miko and Boldur that I was struggling with. Attikus now has a silence as a basic ability and gets a wound debuff much earlier than Pendles. I’ve only played one Attikus game since Pendles dropped so I don’t know if he’s a counter but he’s bulky enough to be an unattractive target for a opportunistic assassin most of the time.
Kleese: Setting up linked Rifts and upgrading the taser makes for a very bad day for an unsupported Pendles but in an opposing team with good timing I was often unable to set up at all.
Orendi: I found myself in a team with an Alani player and a Miko so again I have a non-support game and played Orendi in a defensive role trying to keep Pendles off the healers. He didn’t stop targeting the healers but with a lot of damage plus reveal meant any kills he got were pretty costly. Orendi is also able to pursue if necessary.
There’s probably some better examples available but these are my experiences. I don’t usually play dedicated Melee characters so I don’t know how characters like Rath or Phoebe deal with Pendles.
