I have always kinda had a hunch that this is wat yu should do but what about soloing over complex and fast progressions that change key? Maybe it's just casue my ear still isn't great that I think it would be extremely difficult to play over these, maybe it actually is.

The reason you're finding this progression difficult with pentatonic scales is that E minor pentatonic is a better fit because the A chord is not in the E Major pentatonic scale. To play the E minor pentatonic scale over your E-A-B progression, the chords would be played as minor chords because the are Perfect Intervals and perfect follows perfect (Em-Am-Bm).
If you wanted to play E-A-B as a Major progression with the emphasis on E you could play the E Ionian mode (E Major Scale).
