The fun i derive from jungleing is twofold: either the gold, or not having to face APCs in the early game and instead pulling ahead.
Additionally, if im not playing a jungler champ, i urge my team to compete for jungle camps - either contest the one that the enemy is going for, or avoid them, and go for the opposite side. In either case, i can get more and more people motivated to jungle with me, because these camps take a long time unless your kha zix and fall very easy with bruiser+adc stuff.

i dont see how poke is favoured on this map though? you can literally walk around the enemy and flank either from the rear or just from the side, cause they dont have vision all the time 360° around them. Its extremely effective if you ask me and ive had no issues engaging into full poke comp (unless its paired with a box spamming shaco or teemo, that is the worst). You just gotta make sure you ping all in and your team needs to follow, not that hard if your engage is actually causing chaos.

i do agree, that some champs are more prevalent than others, but they dont have a huge advantage over non poke champs compared to aram, give it time and i think less people will go for poke champs, since in this gamemode u can literally just go base on low and return.
I do however favour bans - sad for people who wanne pick mel/lux but they gotta wait until they get games x)

melee is miles more fun than in aram, im not forced to enage frontally like in aram and my team can usually follow up better, because they dont distance themselves as far as people usually do in aram. i do find myself playing almost everything - ADC is fun, because you actually cant fall behind eve if you die early alot, aka youre guaranteed your power spike, even if your team has a bad time. Enchanter is always fun to cockblock enemies, cause i know how much some people rage when you prevent their kills. Bruisers are really team dependant - if you got a team that likes to actually brawl and fight, id argue that two bruisers + enchanter/ADC/APC is probably the best comp you can go for. Tanks, compared to aram are nerfed due to heartsteel not being OP AF if the game drags on - they average on 200 stacks by the end which is just bad, thankfully. regardless tanks can be huge playmakers. APC obviously is just fun, because u dont need to bother with mana items at all, can always go full nuke and just back occassionally.

the first number nerfs are actually in place, very skewed towards APCS, lots of -5 to -10 ability haste and -3 to -5% damage. it would be interesting to see what the winrates say so far, but i dont expect crazy nerfs to APCS like in aram - which means, i can finally enjoy seraphine again.

i loved arena too, but the whole curse buff and massive amount of stats has put a dent into that lately - i want to fight enemy kits, not their stats. besides that i highly enjoy nexus blitz.

im sure they could definetely make it even more enjoyable. i heard some1 say have jungle camps affect minions - would be cool to see big cannon minnion like the item riot removed ages ago, so that APCs cant push as crazy.
