I've been out of this game for... a long time now. Not since War of the Light II. Since I no longer have my member ship and by association all episodic content, how do I increase my CR from where it is now (112) to max? None of the vendors show anything because I haven't paid (I assume). Thanks!
They changed processes since your original playing time and now offer event versions of new content that can raise your cr. The vault also gives a piece of scalable gear a day now.
Also, read up on some of the other "returning player" threads. If I'm not reading too much into your OP, there have been some major changes since the time cr was king(Artifacts especially).
