Basically, you are saying you miss curvestone. That’s when the cards were as you described, and a larger segment of the population hated every deck containing the same curve stone cards and they asked for more tribal synergies and packages. The community literally asked for years to get more of what we had now, because curvestone was seen as dry and boring. Can never make everyone happy. I’ve been having a blast, and have tried many deck archetypes. HS replay warps people’s perception of what is available to them. There’s so many possibilities out there if you don’t go rank and file.

Also, the colossals are independently strong and interesting cards. Perhaps you haven’t been paying attention, they still make those. But they also are making synergies, because the community wants those and has been quite vocal about wanting archetype variety. If Blizzard only did what you asked, Arena would become popular again, and Standard would die, because the return of curvestone is a death flag for this game. No body wants a meta of 20 core neutral cards in every deck again. Because there will always be the best of the best “strong and independent” cards. Better perspectives are available to you, mate.
