I posted some of this in another thread but I think that it warrants proper examination and ideally comment from Kabam.
I’m going to take you on a little journey of my BG experience this season so far.
With the launch of BG yesterday I loaded up my deck. The deck I’ve spent upgrading since the betas were launched and it’s in a place where I’m very happy with it. It’s strong, it helped me get to Mysterium 1 last season and as I said, is the result of months of work:

This deck will only fight players of equal, or in many cases, greater strength than my own as it’s probably in the top 2% or so of players, at least until I reach the circuit and matchmaking opens up a little bit. The highlight of this deck’s experience was this absolute unit who I only beat because he had an absolute ‘mare with my Doom:

I then saw a topic discussing prestige, or deck prestige as the major factor in matchmaking and decided that as I had full energy and bronze III is low stakes I’d have a bit of fun and see what happened when I switched my deck up.
I loaded up with only my 5*, mostly max sig 5/65, a pretty decent deck and representing my Cavalier days before 6* were so common and R3s were a myth unless you owned a Ferrari.

This is what I was matched with:


Two decks one stronger than my 5*, one weaker but both representing different stages of game development and ability.
I then decided to go further, and switched it out for my 4* and R3 5*, curious as to how far I could affect my opponents simply by changing my deck:

This is the poor guy I matched, a complete newbie whose 3 developed champions were obvious instant bans leaving him with virtually nothing in the locker.

I then switched out these for my 3*, and having ranked a good deal of them up I’m able to make a pretty ‘meta’ deck.

This was the point I was thinking that I’d come up against a sweaty Paragon trying to creep under the radar, and guess what, I was right:

All max 3*, capped by a Platpool profile pic (cropped).
After putting this guy to the sword I then loaded up my 2* - all of which are maxed, so stand by for some 2* Mojo and Korg action:

The rot goes deep, this was my opponent, and he was good too. I’m not sure if this was an off game for me, but he was certainly good enough to be playing with his proper roster rather than sneaking around down here - unless it was research too:
