Why Smite is BROKEN in Season 5
First off, let me give you a hint of what the season 5 smite changes are, all summarized in a nutshell for you: http://www.surrenderat20.net/2014/10/109-pbe-update.html
Anyways, let us begin the discussion on why smite is BROKEN in season 5 as it currently stands and why it can be EASILY abused by people.
First off, the identity of smite had been completely lost with the ability to smite OTHER CHAMPIONS with a hunter's machete enchantment. Before these changes, smite was a spell that people knew as one to conquer the monsters or secure a buff. These uses were defensive and promoted defensive play (with possible offensive uses, but mainly defensive), but now since smite can be used against champions, it's a completely different thing. While I do agree that junglers need a buff, this is not the way to do it as now smite promotes extremely offensive play, and it has lost this identity. Not to mention, Laners can pick up smite and a hunter's machete enchantment to end up with a summoner spell that is probably better than ignite itself.
Now my second part mentions how smite can be easily abused by laners to gain an early advantage and eventually snowball. LoL is already a game full of snowballing, the first 10 minutes can decide the entire game (cough cough Worlds FInals). Now, the buffs that people recieve when they smite a neutral monster can be abused by laners to gain an easy advantage with a neutral monster buff. Laners can take smite to easily get a free buff for their lane and pretty much win it
If you don't understand, lets say that a tristana ADC takes smite. He leashes the jungler until Krugs and smites it for a buff that gives him execute damage. Now, the tristana is acting as such a huge lane bully with her support and ends up snowballing, carrying, and winning the game. Why did this happen? Because the Tristana took smite and got a free buff early - and this smite abuse can be transposed throughout the entire game - not just the beginning.
Rito, we need to fix smite before season 5 begins.
