So. Longtime player, heavy supporter of SSG, and DDO. Not gonna say I outspend everyone, but I Rank.
I have been silent about reaper mode; no more:
Reaper Mode Sucks and it is not Dungeons and Dragons.
SSG you cannot compete with games that offer progression similar to Reaper Mode. All of the games that use that system do it better than you do.
You created a problem with AC, PRR, and MRR and Dodge. These need to be adjusted slowly and frequently until it is solved. A good suggestion is to merge AC and PRR. (Strimtom credit).
Addressing the stat crunch could be done by adding in a CORE mode balanced around 32point builds.
Consider allowing NO previously earned gear into this mode.
You could allow for randomly rolled items for slots at a chest at the start of the quest. The more party members the more choice as loot can be passed and traded.
Leave TRs overpowered, and don't give those players a challenge. TRing for more challenges is the logic of a fool. TR completionist is enough of a challenge.
REAPER MODE IS A CASH GRAB, AND OTHER GAMES DO IT BETTER.
Focus on bringing this game closer to dungeons and dragons. Add languages, add detect magic, and read runes. Incorporate that into character creation and the quests you make.
