My discord was hyped about hopping to get gible from this event, mostly because its Gible, and its an egg boosting event.
This isnt a whining and complaining post about the death and destruction that will ensue in some players from not getting it, but rather a thought one.
Garchomp got Dragontail/Outrage, from what has been found in the code, information that was accurate to the other movesets of various pokemon, so I think we can take this as it will have the moves that were found. As an attacker, will there be much reason to not evolve a gible and wait for a community day was the question my discord was debating about.
Peronally, I feel theres no good answer for this. On one side, we have something with near dragonite attack stat, but much more bulk and one of the best generalist movesets in the game, and one of the best ground sets it could have gotten, though that isnt saying much so it would be an invaluable member of almost any team. While the other side would be look at the starters moves and meteor mash metagross. Imagining a pokemon like garchomp with moves like that is a terrifying thought as to what the pokemon could do.
With the double moveset being a thing now, a garchomp could carry some hypothetical CD move, and the best move of its other type, but waiting wuld also mean you are without one of potentially the best attackers of gen 4 for a while. (if we get a bagon CD febuary, then following the 4month pseudo legendary pattern, gible would only need to wait until june)
Personally, and I know im in the minority on this, im hoping they give garchomp dragon rush, Gigaimpact might also be a possibility, give it is a very notable use of that, but the same can be said for it an dragonrush. A lot get annoyed at the dragon's preferential treatment, but they get it for a reason. A good ground set on it could be good, but Precipice blades on groudon looms over even groudon.
