I always wanted to see how this would play out.
My idea was to have the following 5 tanks/Tanky DPS:
1. Galio (mid)
2. Garen (top)
3. Rammus (jungle)
4. Mundo (bot) {damage}
5. Amumu (bot) {support}
Items:
Warmogs
Thornmail
Force of Nature
Boots
(Main Item)
(Main Item)
The goal is to make the entire team balanced around survival and defeating people over time than quick bursts. Since they are already tanky, they should lane well and with Range not being an issue for Bot as Mundo can throw his cleave and amumu can stun, I think bot lane is OK and difficult to gank as they wont blow up as easy as other champions since they are tanks/tanky dps.
PROS:
1. Survival
2. AoE potential
3. Ganking is medium-high
4. Average damage
CONS:
1. Slow Lane for Bot
2. Burst is low-medium
3. Item heavy early-mid game
4. Longer game (most-likely)
