As the title states, it’s far too powerful if you random a pre-Built structure from Grimes.
If you changed Meltdown because it could be played too soon and cause far too much random damage, thus ruining games, it made sense to increase it’s cost and change it’s stats and damge.
If you changed Chrysalis Burst due to the possibility of randomly getting way too powerful minions early and the opponent not having enough turns to possibly answer or play around it, it makes sense to increase it’s cost
Now, I love Duelyst because of the board, I know there will always be a roll in chance of what I draw/replace and what my opponent does too but most games will revolve around skill, knowing where to place minions, when to play minions/artifacts/spells, when to set up minions/artifacts/spells etc…
However it’s annoying and boring when a game is won or lost due to randomly getting something that completely changes the game, which is why 2 cards I mentioned above were changed, which on the forums/patch were explained why they were changed yet this can happpen.
So, the new Build mechanic came out and I like the idea of it, set something up and try to protect it, if you succeed you are rewarded with something powerful. Some being stronger than others.
Grimes ruins this, you don’t have to protect the structure for a certain amount of turns because hey… it’s already Built!!!
A little random is fine, too much kills the fun and joy of a WELL PLAYED game.
So in my opinion, ok, let Grimes have almost any possible minion but structures that are fully Built? No, a complete no. Some are extremely powerful, especially Abyssian’s "Gate to the Undervault".
If you want to have them being Built, that’s fine, but pre-Built, no
Please keep this game skill based
If you want to have a “For Fun Mode” then add a separate mode or game type for that, not in Rank.
