Season 5 vs Season 4 Jungle
Season 4 Jungle - Which Junglers thrived best when given large amounts of resources (short smite cd, more camps, faster respawn times). Season 5 Jungle - Which Junglers aren't complete garbage at clearing and can still gank with a small pool of resources.
Riot intentionally designed the jungle right now such that it would be PUNISHING. They wanted Junglers to decide between farming and ganking. They didn't want it to be a competition of who can do it all the best. Unfortunately, WE ARE STILL IN THE SAME SITUATION. The Jungle is STILL a competition of those who can deal with it the best, fulfilling all niches as generally as possible. Unfortunately, now we have to deal with 5 top tier picks with every other Jungler being significantly weaker than the top.
Season 4 Jungle - A multi-tiered Jungle with even champions who faired poorly in clears being playable thanks to sustain being prevalent and numerous resources. Season 5 Jungle - A two-tiered Jungle - Viable tier and Shit tier.
You made the Jungle harder but didn't COMPENSATE Junglers for it. Overall, we make LESS gold and get LESS experience than last Season. You took away our options, and you didn't give us anything back. The only option in the Jungle right now is GANK because assists (and lane tax) give the most gold and experience out of anything else. OF COURSE Jarvan and Vi and Lee are going to be strong. You built this Jungle from the ground up for them to survive in. These champions can actually clear AND gank - they don't need experience or gold to do it either. In fact, ACTUALLY CLEARING is a precursor for ganking. Nobody can gank a level 7 mid-laner as a level 4 and expect things to go well.
Not to mention how your numerous vision changes have indirectly nerfed the crap out of Junglers. Wolf-smite, Scuttle Crab, Trinkets, CHEAP trinket upgrades. Vision is more prevalent and cheaper than its EVER been in League of Legends. There is no trade-off to lighting up the whole map. OF COURSE Champions with multiple gap-closers are going to be strong. Not only does every champion in this game have FLASH and a DASH, but they can also SEE YOU COMING FROM A MILE AWAY. If I don't have high-mobility and burst, I'm basically useless in this jungle.
I think Riot has taken the wrong direction with this Jungle. The NUMEROUS blanket nerfs across the jungle have completely buried anybody who doesn't fit the niche this Jungle was designed for. LESS resources means LESS viable strategies. Riot, this Jungle needs a LARGE overhaul. I don't think small tuning can fix it. I don't know how you are going to approach this monster, but you've pushed the Jungle so far down the wrong path that it's going to be hard to recover mid-season.
