From playing 1 Jhin game in custom, you can't spam grenade. Not sure on the actual mana cost but having mana issues was the biggest thing holding me back against the bots
Regarding Udyr, I'm going 100% Diana/Udyr now. Played 4 games last night as Udyr and went 2-2 but should have easily went 4-0. I hate to blame teammates but yea... Losing games going 8-2-8 and 9-2-8 is super sad. That's 16 of 18 and 17 of 21 kill participation in those games. Only thing I could have tried was playing the split push game a bit harder, but no guarantee it would have worked.
Considering I've only played 2 Udyr games in the past year... and they were both top lane, I'm not too sad about losing those games. I need to refine strat & build a bit better to handle deadbeat teams more. Still rocking a 6.50 KDA in 4 games with 5 of my 10 deaths happening in my 1st Udyr game this Season. Seems strong as fuck and I hope to ride him up the ranks with my usual Diana pick.
Speaking of Diana... Either I lost my touch, the meta has shifted, or I'm super unlucky... but my games have been really tough with her and I'm not stringing together the wins like I was a couple months ago. She can still get fed and carry but it just seems a lot harder. Not much has changed since pre-season except people are try-harding more now and also Dynamic Queue puts everyone in their preferred roles, so matchups are always going to be tough. I also blame Maw of Malmortis... seems like every AD champion buys that thing (because it's OP as fuck), and it seems like nobody purchased it in pre-season.
I've been stuck in Gold I for a few weeks now (climbed from Gold 5) and only have a 51% win rate with Diana after 91 games (literally 46-45 record with her). I've played 103 ranked games this season already and am at a 47% win rate. 0-8 record with champions other than Diana & Udyr
Picking up Udyr should be a big help. I tried Volibear twice when teams needed a tank in the jungle and failed both times. Udyr is strong and will fill the role much better.
Here's my Udyr builds from last night, only thing I can think to do with those losses was split push and build a Zzrot portal to aid with that. I've been checking out Trick2g's builds for inspiration on what to buy:
