No. The content was good but they've could've done alot more. Tom Lee mentioned before LR release that they would likely offer different things besides costumes and characters as DLC.... What ever happened to That?
-5 vanilla had 5 new characters added total, Ultimate had 8 added total(3 as DLC) and LR only had 4(two as guest DLC characters). Them adding Mai literally a year before they'd discontinue DLC and support of the game imo was silly and pointless, like they could've just waited till DOA6 to add her.
-Only three total stages besides the added Crimson and Danger zone were added in the 3 year time span.. That's kind of sad imo when compared to other games.
-They could've added additional story DLC for the new characters and they could've further balanced some characters so they would be better up to par with the rest of the cast
-They could've added more hairstyles, glasses etc. since the new UI for editing details and hair on costumes was a good foundation for this. They could've also done more graphics wise since the game basically only had better boob physics and a better skin shader slapped on ps3 last gen models. They could've also patched in the soft engine 2.0 and made the girl bodies on par with how they were in X3. Hairstyles that were exclusive to set costumes could've also been made to be universal.
-Story mode content such as the subway car, freedom survivor, destroyed lab, Rig phase lab and the inside of the Taylor Bar could've been made into new stages, including that cut transition that would have happened in depth. That Kasumi alpha 152 boss costume could've been used on phase as a new costume.
Basically in general no, DOA6 should not go down this path. I get they probably d idnt wanna do much more since LR is basically just a PS4 port of last gen DOA5 with additional effects and skin shaders slapped on ps3 assets but it could've done more. Since DOA6 will hopefully look way better than DOA5, Nioh and X3 they'll be able to pull out all the stops so they can continue to support it even longer. DOA5LR was a good game but they still could've done ALOT more, both content and looks wise
