Elemental dragons were a project condemned to fail
It's been a year and something now that we have them. The goal was to force players to change their strategy depending on what dragons they get OR take dragons only if they fit to your strategy (teamcomp mainly -> splitpush heavy teams would take Cloud, Infernal for teamfighting, Mountain for sieging and Ocean for poking - which actually overlap a bit anyway).
And for this period of time, did any of you ever take the dragon for one of these reasons? I personally didn't and nor my teammates ever. It still stayed the same: Can we get the drake? Let's take it. Can we not? Let's not. Is the enemy doing the drake? Stop them.
Now why did I say it was condemned to fail? Simply because it's a free benefit when you can take it and it's nonsence to ignore it when it doesn't fit into your teamcomp because you would be just providing the advantage to the enemies.
Then we have the second, more realistic goal: So each game is different from the other. Do elemental drakes deliver this feeling though? The games are already different based on enemy picks, which, although people spam meta picks, still affect the diversity way more - hell there are 130+ champions! And they can appear in 5 roles (although most cases never happen - like Nunu ADC)! Are 4 types of dragons (+ the Elder one which always spawns, so no diversity here) capable of matching that? No way!
I don't say I hate elemental dragons. Yes, I'm not fan either, I don't care mostly - and that's the issue, not counting the release of them (balance problems, as usually), noone really cares. And the main problem Riot had with the dragon was that people didn't really care except the fact that having the most is the best option, which is completely identical.
I just share this opinion. I have no real solution to this problem, mainly because I don't feel like there was a problem with dragons. I would like to know if anyone else feels different about this topic.
