[PSA]: Always Take Smite if you Jungle
If you are assigned or Queued up for Jungle, always take the Smite
summoner spell with you. If you would like to use something like ignite or Exhaust with you, substitute your flash instead. Normally Flash is extremely important & is used by 99.9% of all players, but Jungling is balanced around the Smite Spell & you will be at a MAJOR Disadvantage for not having it.
Here's an example, I played a game of Solo Queue just the other day where our Jungler chose Flash/Ignite as his summoner spells (This was done intentionally, but that's a post for another day). Since he did not have Smite, he was at a EXP disadvantage for the entire game. By the time he got to Level 2-3, all 9 other players had reached Levels 6-7.
Once again I ask that if you Jungle, please take the Smite Summoner Spell with you. Also worth mentioning, You can also run Summoners Spell book, but make sure you equip smite in Champion Select so you can buy your Jungling items (which give you Bonus EXP that is Quintessential to Jungling, can't Jungle without it).
and
should become available without smite, but not allow you to upgrade into
,
, or
, so that you won't be screwed out of experience just because you failed to start with jungle items.
