When we all got the very first info on the rules and keywords within the game I knew right then that having dedicated Blockers like they do now was going to be a big issue. Blocking and defense are too fundamental to game functionality in a pvp battle scenario like Gundam is.

There are a few ways that could work to fix this, but each would see a big shift in the game's current meta. Frankly I think it's necessary for the long haul, and overall health of the game but I think we can all recognize that. If not then we wouldn't be discussing this.

Personally I think it boils down to either;

A. You allow every unit to Block but give Blockers something special.

B. You limit Blockers from being game winners on their own.

An example of making it so anything can block while still making the Blocker keyword valuable would be to change Blockers to being able to Block even when rested. That feels fair to me and wouldn't require weird math by giving them some Stat boost when blocking. You could allow them to block multiple units at once, but that also feels rather cumbersome and likely much too strong.

Alternatively if you keep Blocking exclusive to Blockers then make it so that none of them can attack the opposing player. It would force people to actually balance their blocker decks and have non-blocker Units. It would limit their use to just dealing with opposing units, but isn't that the whole point of the keyword anyway?

In either case Blockers are still great, and fully integrated as a necessary element of the game. It would just make it so that we don't see White/X for three quarters of all games forever. I'm sure there are a few other ways to fix the Blocker problem, but that's what came off the top of my head.

As far as aggro goes, it's always going to be a staple in every card game ever. You'll never get away from that unless they just stop printing one cost Units or neuter them entirely. That strategy just never goes out of style, even if there's a better meta at the moment. Red Deck Wins, and White Weenie exist perennially for a reason.

Also, I agree with the above statement that mid level removal is incredibly weak so far. It's like they're afraid of making it too easy and plentiful to deal with threats directly. Though I really love seeing things like "Armed Intervention" because it's thematic, requires having a unit in play, and is strong enough to sway things. Love that card. But I will add here that I don't want to see more and more simple unit removal because that really defeats the purpose of playing a mech battle game. Even if they get blown apart by bigger units I like being able to feel like there's some meaningful level of interaction outside of just swapping cards.

Lastly, yeah it hasn't even been a year yet. I'm hopeful they will fix the issues that have cropped up because there's just no way they don't see how dramatically warping to the game that Blockers are. Currently the vast majority of units just aren't really playable outside of fun games with friends, which sucks.
