As a Jungler main I actually love the new map, the fluidity of it all after I got used to it, plus the enhanced vision, items, and objective control makes for an extremely interesting setup...and lets be honest the only thing that really changed were the graphics, jungle, and a few new items...otherwise for Laners its exactly the same...3 towers, 3 lanes, nothing else to do but farm and kill. Objective control is even more important which is great, you get a real advantage from controlling Dragon, and a real advantage from having Baron besides "LOLGUIZE WE GOT BARON LETS SMASH" Taking Baron was ultimately giving your team Red and Blue Buff + some extra damage...nothing special about that...Now you get buffs that are actually useful outside of mindless Regen that most people wont notice if they were just diving into the enemy team because "LolBARONBUFF!" The Addition of the Mud Crab camp in the river allows Junglers to help their Laners be more situationally aware and isn't that hard to kill quickly and move on...and is especially worth while if you have terrible Laners that don't ward often enough or don't ward at all. Yeah they killed the early Jungle Agression Pre-4 minutes but honestly it takes a load off our backs...because now people understand if a Jungler can't gank post 3 right off the bat. Clear 4/7 and back, get your 2nd Tier Item and reclear til 6 or look for an easy gank depending on the jungler (i.e. Nautilus and Maokai who doint need their ults to gank efficiently.)
Honestly if you can point out whats changed for Laners I'd love to hear it...and if you're a Jungler...well maybe its time to break your habits and readjust...once you see how awesome the new jungle is with all of its buffs, choosing when and what to smite (i.e. Smiting Chicken buff mid and late game to clear Wards, or Frog and Golems early for clear speed or survivability) Not to mention the new Jungle Items...having so many choices is just a beautiful thing and really allows you to tailor your play to the situation. Sorry that you're having such a hard time, but hey...nothing changed in Laner Play, everything changed in Jungle Play, and
has become Queen of the Jungle :)
