Sniper - Allyourtowersarebelongtome

Here is some patronizing: "Allyourtowersarebelongtome", All your towers are belong to me.
*All your towers belong to me. That's all.

Actually, this is super viable at my level of play (mid level scrims). You almost always see maxed shrapnel at 7. Not only is it pretty good for tower pushing but it's your only semi-okay way of getting out of gank with the slow.

The damage type is magical. Tower's have 0 magic damage resistance. Thus any damage dealt by shrapnel is true damage.
It deals 13.2 damage per second for 9 seconds, resulting in 118 damage. The only reason this is good, is the cast range is longer than your actual attack range. As you can easily cast shrapnel on a tower from a safe distance from harm. I personally agree on not using this strategy though. In low rating games, its a very effective way get an easy tower in a solo mid lane.

If you want to push, I really don't recommend picking Sniper.

I think that getting range farther than the tower is better than doing 98 damage to it.

shrapnel does 30% dmg to towers, this is about 12+ at its highest rank. 12 times 8 is 96 which is a respectable amount.but tower armor ensures that little damage is taken, it is good however early on when attacking the tower would be suicidal.
