Let me weigh in briefly on this thread. I haven't been with IW as long as many of the players contributing their feedback on the forums but as part of the dev team, I do have more perspective in some aspects than others.
The current state of constructed play (ranked and normal) are right now a little stacked towards fast decks, chief among them FD based decks but other metas that are able to ramp quickly and smoothly have a significant advantage. will we be looking at rebalancing the metas in the near future? You bet.
From a personal time-division perspective, I've so far been spending a lot of my time focused on a few big areas of change that are very necessary to the long term health of the game. Firstly lots of changes targeted at the new user experience, most of which no one outside of the dev teams has seen yet because there are lots of pieces that are being developed in parallel.
Second, I've been focused on one of the fundamental gameplay impacting issues which is desyncs. You've started to see some of this with the new desync trap going onto the PBE and soon to be the live servers. Already, the desync trap has helped us to identify and fix dozens of previously unreproducible desync card behaviors quickly and effectively. Just 2 days ago, Mattcledford and I triggered the desync trap twice on PBE which allowed the dev team to immediately identify, reproduce and fix the 2 offending cards within hours.
Third, I've been spending a lot of time on draft mode as a player so that I could gain a better understanding of what needed to change with it and you're all just starting to see some of the improvements coming through with the new Rift Rewards, Cultivated draft, etc.
The next BIG thing for me will be moving my focus over to Ranked once the dust settles on big changes on the draft side. There are many things that we want to overhaul with Ranked and constructed metas will be a significant part of this. Other areas that we'll be looking at very deeply will include the ranked score algorithms, ranked seasons taxonomy and rewards, etc.
Just like with draft, I don't like to make significant changes to a system until I've personally played it to death and fully understand the nuances of what make it good and bad. Expect to see me playing a lot more constructed and ranked matches in the near future as I plan to familiarise myself much more deeply with the game mode more intimately. If I ever manage to climb high on the ranked leaderboards, you'll know that I'm ready to make some signficant changes.
As those of you who know me will know, you can expect that I'll be reaching out personally to many of you to get coaching and feedback on ranked play soon.
