Almost all AD champs are easy to take on with Rammus but the AP champs with CC stuns can be almost impossible to kill if they are ahead of you in both gold and level, even by a small amount. Best to stay clear of these champs unless you have backup until you have some good magic resist items. Don't chase them when they are low for a kill EVER! .. Go for the enemy ADC first with a thornmail and wait until late game to take on the AP stun champions.

1500 games of Rammus pre rework and he got me to PLAT but i played like a Rambo and died allot in most games.

THIS new reworked Rammus is both good in some ways and bad in others!

At first i HATED the new Rammus in every way and i was losing more then winning. I still despise the 60% slow on his W but with the swiftness mastery traite its permanently only a 48% slow. Grab some swiftness boots on top and it becomes a 33% slow. ( i'm fine with 48% )

100 reworked Rammus games later.. (YES its taken me 100 games with this new reworked Rammus) I am now back to winning MORE then losing .. In fact I'm winning with more kills each game then i was with the old Rammus and this is due to two reasons.

Reason 1. The new Rammus forces you to play SUPER SAFE early game and i mean super safe plus he also forces you to HIT W and fight until the enemy jg invading runs away or you die in early game counter jg invades. THEY LOSE THE INVADE most of the time though .. No joke AP OR AD champs i win the invade. I never used too with old Rammus. BUT with this new rammus you CAN NOT run away as easy as you used too and his W is much stronger at level 1-2 with no items.

Reason 2. His ULT (R) does next to no damage but the 15 to 80% slow for 6 seconds is insane ... NO ONE without flash can run away from you and the 6 second cool down on Q, W and E is nuts! i used to always need to run cool down reduction runes but now i just max Q first so all my abilities have 6 second cool downs and I'm set to never let them get way .. Just need to always remember to turn OFF W and that is the reason everyone hates the new rework. They are not used to turning W off and on all the time.. ( its annoying but a must do ).. It also takes a very long time to get used to turning it off and on when needed.

The only damage item you need to dominate with Rammus is Liandry's Torment as your Forth or second last item.

It now does double the damage when using your ULT (R). IT also proc's with your shield (w) on whoever attacked you .. So with Thornmail and W turned on if they attack you they receive thornmail damage.. W damage and 2-4% of thier health lost from Liandry each second..add 15 magic pen as a bonus boost to thornmail,W and Liandry's it suddenly becomes a really bad idea to attack Rammus. He also gains 2% life steel when being attacked with W on.
