Before you complain this is not a thread to trash Palps or say he was weaker, less skilled or anything of that sorts. But to say that SPECIFICALLY as Sith Masters for Vader I think Plageueis would had made a way better job and perhaps would been the most suited Sith Master for him. Think about it, with Palps: - He got into a suit, that is hinted was even made to be as limiting as possible to be easy to control. - After Mustafar forever got crippled - He learned little from Palps, who was holding a lot to himself. - Had no real motivation to live In short he got duped and from the momment he got crippled it seems Palpatine tossed him like "Meh, another useless apprentice I will replace." Just imagine Vader's potential with Plagueis, even assuming he got crippled: - Even with the suit with his midichlorian manipulation and Vader's force potential it would had been a matter of time before Vader was out of the suit and on his way to regain full potential again. - Imagine Vader's potential with midichlorian manipulation - Considering the resurrecting possibilities of Plagueis's studies, even if Padme died Vader would have a real motivation to push himself to its limits, as he would be fighting for the chance to resurrect Padme. - Consiering Plagueis really got attatched to Palpatine his apprentice, it is unlikely he would had held knowledge back if Vader became his apprentice Agree? Disagree? I personally think that Plagueis ironically would had been the ideal Sith master for Vader. "What if Plagueis were Vader's Sith master guys? Talk about it!" Bedlam, come on, this is the third "What if" thread you've posted in three weeks. Cut it out.
