This is something that I wanted to talk about for a while. If you look at some of the recent top tier decks that used Demacia ( Sivir/Akshan, Poppy/Zed, Pantheon) you notice that it is is mostly used as a support region, you basically use Demacia whenever you need the following cards ( Single Combat, Concerted Strike, Golden Aegis, Sharpsight, Brightsteel Protector ).
Barring a few exception Demacia's followers and champions don't seem to make it into competitive decks, the reason for that is, well at least in my opinion, is because Demacia lacks finishers unit's that can ignore chump blocker to deal damage directly to face, most of Demacia champions and followers are good at trading but they struggle with closing the game.
Regions like Shurima, Targon and Ionia tend abuse the above cards because they have access to unit's with overwhelm and elusive. If you opponent use a Cataclysm on Jarvan IV that just mean your going to lose a unit but a Cataclysm on Pantheon usually mean that you will lose the game.
Taking all of that into account it's no surprise that the Demacian champion who had the most success in the competitive scene is Fiora because she had an alternate win con, that also why Jarvan/Shen could never be as dominant as Fiora/Shen despite sharing 90% of it's card with that deck.
So how do we fix this problem? how do we give Demacia finisher? Well the obvious answer would be just give them unit's with elusive or overwhelm. But that just seem to be a lazy fix to me, plus elusive does not make sense from a lore perceptive ( Demecia is know for it's big mighty army, that is as far from stealthy as it get's ).
The first one is fearsome Cithria the Bold is one the few, good Demacian finisher having seen play in both MF/Quinn and Fiora/Shen and what does she do? she give your board fearsome plus a stat boost, plus it fits from lore perspective big armies are fearsome and let's no forget about the anti-mage secret police that kingdom have.
The other mechanic that comes to mind is the very underused give unit "can't block," Demacia is know for petricite a substance that nullify magic, mageseekers use it to restrain mages preventing them from defending themselves similar to how "can't block " prevent your opponent from using his unit's to defend his nexus.
Anyway this post ended up being longer than expected, so what do you guys think?
