User blog comment:NicknameMy/Rework for Tiamat, new tier 3 tiamat/@comment-86.29.128.242-20120321205620

we only really need a splash range increase. I like the current Damage+regen stats we currently have on tiamat. the problem with tiamat is the splash is so very small that it's pointless to have unless you only ever want to hit creeps. Also, the lack of an upgrade for it (a common problem with items. Executioners, Guise, old hexdrinker etc) so just add an upgrade path and a splash range buff on the upgrade and we might see tiamat as a viable item.

Finally, you can't use the lane pushing argument with these items because by the time you get them, lane phase should be over. It's not like it's the type of item you would rush anyway. more for mid-lategame pushing and teamfight clumping punishment.
