Yeah, Cass can be difficult. Zilean is fun, but he is a little more on the support side. I bought Ziggs. My initial thoughts. Powerfull. Some of his stuff has tricky aiming. Learning his Q (bouncing bomb) is what seperates the good and the bad ziggs. But he can have a ton of burst damage, and he can have a lot of really clutch moments. +Tons of damage +Good ratios on skills (mainly his ult) +Decent CC (knockback and Slow) +Good range harrass if you can land Q +Good burst +AOE NUKE. -Can be hard to land Q and range -Squishy -Runs low on mana fast withought blue buff Overall a good caster. He is on the edge of OP. Good build: 3 Dorans rings to start, gives that HP+AP+Mana regen that you need early. Sorc Shoes to get some magic pen RoA or Rylais for tank-AP items. Both are good choices. Rabadons for sure. Rylais if you didn't get it Morellos Evil Tome is great for cooldowns and mana regen.
