i'm afraid of the new titanic hydra + deadmans
this is going to be a scary combination. imagine this on auto based champions like irelia and jax, the tanks already do pretty high damage and this is going to agitate the situation more, most tank items already have hp built into them, deadmans stats are going to compliment titanic real nicely and the passive gives champions more movement speed, a 75% slow at 100 stacks, and bonus damage according to how much stacks you had.
get a trinity, deadmans, titanic, and full tank from their and your going to have pretty high hp, some decent resistance and high ad the equivalence of additional 1 or 2 offensive items. the draw back is being that this probably will only work if you manage to get to late game and full build.
and
to start gating you, lets just say it helps, it doesn't solve all your problems, but it helps.
