Cloud drake right now is pretty pointless. The best reason to take it is to get the next dragon to spawn. and pray it's something different. Giving it 5% tenacity per stack could add some real value to it. There isn't much in the game that provides tenacity and it could really give a team an edge in a close fight. And it would fit well with the theme of the cloud drake.
Lazypeon1001 votesI think this would be a bad solution. The whole point to cloud drake is supposed to be mobility. Tenqcity would end up either bringing too much strength to the table (and being over bearing really quickly on many champions) or would be useless (thus not solving the issue) depending on how it is tuned. Thematically, tenacity would also be weird on cloud drake.
bulldoggamer1 votesRight now all Cloud drake provides is minor rotational power. Tenacity reduces the amount of time your mobility is reduced, thus fitting the mobility theme. Being able to get 15% tenacity would be strong, but no more powerful than 24% more damage. And 15% is just a guesstimate on what would be balanced. The only champion i could see it getting overbearing on is Irealia. But she can already get up to 60% tenacity (i think). If it ended up being useless, oh well. It's still better than before and it's a step in the right direction that has more freedom to be adjusted to get to a balanced state. Out of combat movement speed will never be enough to be as useful as % more damage or even burn damage on turrets.
Lazypeon1001 votesI'm not saying cloud drake doesn't need to be stronger, as it is currently weak. But think this would be a problem. Adding tenacity to make it better (even if it ends up useless) just becomes a clouded mess of balance and will confuse players until it is inevitably changed.
If it ends up being overbearing then the problem becomes obvious as we haven't solved cloud drake's problem, just changed it.
Even at 15%, this will encourage many more top laners, junglers, and supports to build into merc treads, as well as making the tenacity / slow resist mastery in the defense tree even stronger than it currently is. There would be outliers like Irellia (which you pointed out) which would also further break this.
I don't really like the idea because of how mandatory it would become, which is flame dragon's problem right now.
bulldoggamer1 votesMy line of thinking is getting Cloud drake to the point where mountain drake is at. It's nice but you can live without it. But to the point where it's worth your time to go take. If it has tenacity attached to it it would provide a small amount of safety against ganks and small advantages in fights. This is in no way a final idea but means of figuring out the pros cons and possible adjustments of this idea. Even if it's like 5 7 and 10 percent there needs to be more of an advantage to getting this objective. And putting more priority on neutral objectives isn't necessarily a bad thing. It would result in more fights and overall more interesting games. I really appreciate your input man!
