Preaseason patch released!

Jungle Camp Experience
Camp monster experience unchanged early, reduced late.

Junglers have been slightly higher-level than intended following midseason's changes to camp experience. With the greater potential for impact that preseason offers junglers via stronger early drakes and a longer lane phase, we're toning the upper end of monster XP scaling down to get them back to their intended leveling pace.

(Note: All values below scale from monster level 1-7.)
GROMP XP115-190 ⇒ 115-172.5
GREATER MURK WOLF XP65-107 ⇒ 65-97.5
MURK WOLF XP25-41.5 ⇒ 25-37.5
CRIMSON RAPTOR XP20-33 ⇒ 20-30
RAPTOR XP20-33 ⇒ 20-30
ANCIENT KRUG XP100-165 ⇒ 100-150 (reminder: first clear still grants 30% reduced XP)
KRUG XP35-58 ⇒ 35-52.5
LESSER KRUG XP7-12 ⇒ 7-10.5

ROW 210 adaptive force (6 AD or 10 AP), 5 armor, or 6 magic resist
ROW 315-90 health (lv 1-18), 5 armor, or 6 magic resist

Teleport
Channel time reduced but can no longer be canceled.

Channeling Teleport is often enough to deter enemies from an aggressive push or dive, even if you have no intention of following through. The mind game is interesting, but should be accompanied by a higher commitment. Laners can still use Teleport to shut down cross-map plays elsewhere, but now they'll sacrifice more tempo in their own lane to do so.

Also, if you pick a bad Teleport, there's no going back so you're probably gonna die. Click carefully.
CHANNEL DURATION4.5 seconds ⇒ 4 seconds
NEWCOMMITTeleport can't be canceled by its caster once cast
