Dragons might allow one team to snowball too easily.

Just looking over the stats, and say one team manages to get 2 internals or 2 oceans, that is quite a damage/regenerative buff over the opponent. The other two can also be, while not nearly as much, overly harmful to the team which did not receive the buff. But I am not against this. My issue is that these objectives still only matter for which team last hits.

Maybe add one or more of the following mechanics,

1. Implement a system that when going for a second or third stack of the same kind of dragon buff, your team deals reduced damage to it while the other deals normal or increased. This would allow your team to still get the buff, but you would have to work a bit more for it. And this seems fair to me since the buffs are quite better than old dragon, and are more punishing for not getting them.

2. Making smite deal reduced damage or not work entirely on dragons which would give you 2 or 3 stacks of a single kind, unless you team has dealt considerable damage already to it (semi-steal prevention, so you cant just jump the wall and steal it last second as easily). Other execute abilities should deal the same damage they normally would (like with Cho'gath's Feast or Nunu's Consume) since those have point blank range and are harder to use in a steal than smite.

3. Make the dragons provide true vision to both sides (while keeping the dragon's health bar hidden) when it is being damaged by a player. This would allow for both sides to be aware of what is happening but the team who is not there would still have to guess on when it is low enough to try and steal it. Wards and players would reveal its health bar if it is in their field of view like usual. This would just indicate that it is/was being damaged by the enemy team. This true vision will not allow targeting abilities, smite or other things like basic attacks to work. It is simply vision of the dragon pit, the game would still treat it as being in fog of war mechanically.

4. Rift Harold and the first Baron after 35 minutes should be considered being added to the Elder Dragon's CRUEL ULTIMATUM stacks if you have less then or equal to 1 elemental dragons stack (still caps at 3 stacks). This way, you can still benefit from a burn stack on top of the base 45 since you have no other way to gain stacks from elemental dragon because just 45 over 3 seconds isn't that big of a damage buff (it is still nice but can be mitigated by other things like Death's Dance passive more easily than 2-3 additional stacks).
