I initially thought this was more restricted than Naboo. But I started preparing both before the raid released and GLLO my highest score in SBR took 6 months for me to farm. Whilst I already have 4 R7 Gungans which has been max scoring 1.8M without Jar Jar and levelling up Quadme R0, MQJ 6 star and POW 7 star (I am no fan of conquest but it was a very easy red crate for me).
So once the strong teams have been solved I actually think it is easier or at least quicker to optimise. My guild is already matching our SBR rewards. For me with less effort as I only have two optimised teams and 1 in development and nearly scoring my equivalent of SBR (the score required is much lower for the same rewards).
There are some very accessible teams for those below 4M and can not get Quadme easily such as Luminara plus kit with any other GR Jedi. These are old characters many are reqs for other journey or GL’s so will either be high relic already or worth the investment beyond the raid. The Maul and sideous teams are also low investment for early game. But anyone over 4M could easily get Quadme MQJ and POW, since MQJ and POW are fast to farm on cantina and even have an AB with shards. The AB also gives them much value beyond the raid and will recoup investment. And low investment Gungans work well too.
The only roster complaints I have heard later in the game are from GL rushers who do not like levelling anything that’s not a GL requirement but to me that’s a personal play style and most of these characters add to rosters. And investing in Luminara and Kit is worth it for 8-9 months raid rewards. Delaying in the hope they will alter will just make the investment less worthwhile later.
Player experience for the minority suffering from the bugs will improve once they fix that, they have been aware awhile so should be something in the works.
