Nexus Siege Tips
Nexus Siege is back!
Unfortunately, tons of people I see have no idea how it's played.
I've got you covered, read this: http://na.leagueoflegends.com/en/featured/nexus-siege
Class Specific Purchases
For marksmen, purchase Runaan's Hurricane 
and Stattik Shiv 
to demolish waves in a matter of seconds.
For fighters, build one of the Hydras 
.
For mages, make sure to buy Lich Bane 
for extra damage against towers.
Strong Sieging Champions
Aside from the ones mentioned in the article, 
, 
, and 
, there are some unsung champions who also excel at this gamemode.
From how well they both destroy turrets, I think Ziggs might be Tristana's uncle. Definetely a stong pick.
Huh, there seems to be a lot of yordles that are good here. Teemo really doesn't have excellent waveclear or tower destruction capability, but no one's better at protecting precious siege weapons than him and a handful of mushrooms.
He's mostly ADC, a slight of Artillery Mage, and has traps. That means he'll push lanes really well, repeatedly force you out of lane even if you're sitting under turret, and defend siege weaponry.
Strong Defensive Champions
, 
, 
were put in the article, but these guys were not.
Time to drag helpless people underneath your tower after using Storm Bulwark.
Why did they not add Ziggs and Heimerdinger on the list presented in the feature? I don't know, but it's nigh Impossible to push a lane with him sitting on it.
Because ADCs cannot push lanes when they're dead.
Thanks for taking the time to read this (or maybe you didn't read anything but this sentence, how am I supposed to tell). If you think I missed something, let me know in the comments.
