So I didn't want to buy this expac as Warlock looked fun and OP, but PD2 has soured me on D2. But then my friends reminded me I could just play a different character since I own d2r. Not the case. I made a paladin and non ROTW characters CANNOT play with ROTW characters. I understand for a variety of reasons, but it eventually made me annoyed enough to buy it. $25 is too steep but hopefully the money is going to the good people at Blizz, if any are left. Then I couldn't figure out how to convert a character to ROTW, but there's a tiny little unlabled button on the bottom right of the character screen you press. I may vary well have been able to convert my characer to the expansion without paying, but most likely not.
That said, do NOT follow the Maxroll guide for Paladin leveling. Holy fuck. The Holy Fire leveling is great and then they have you switch at 19/Mephisto to Blessed Hammers and HOLY FUCK do they SUCK FUCKING ASS in 70% of layouts. I get they're the GG build end game, but without 2x Spirit and some more FCR gear you just sit there getting beat trying to cast two hammers which hit the wall and immediately disappear. Maggot lair was 50 minutes of me watching my merc poke his way through Duriels colon.
There's definitely a reason Paladins are always a 2nd character. PD2 makes leveling paladins fun and easy, but this game, holy fuck. Also you can't put auras on left click, still, even though people have been begging since D2R came out.
