I don't see how it would be very confusing IMO. I enjoyed getting a new name for the flagship pack for each version, but I enjoy infinity lite being the name. Has finding tutorials for the various DW20 packs been an issue? It's essentially the same thing as this concept of keeping the name.
There is a small difference... We only have one "Direwolf20" pack every round of version upgrades as opposed to multiple versions like:
1). Infinity
2). Infinity Lite (Less Filling! Tastes Great! ) (look it up if you're that young)
3). Infinity Evolved
4). Infinity Evolved: Expert (admittedly, a switchable option in later versions of #3)
5). Infinity Evolved: Skyblock
For myself, it doesn't make a difference... I'm capable and willing to read the pack descriptions to see if I have the correct pack, but I'm an anomaly in the on-line community.
