The Magus now keeps me interested from level 1 to 20
the neat new arcane pool is fun and the improved spell combat is now worth doing at the lower levels. i think you balanced the arcane and warrior parts of the class well. the only two things that bug me now
1. Fighter Training why at level 10 your fight level for the purpose of feats counts as half your Magus level why not at 2 level it counts as half or at level 4 you count as your Magus level -3
2. Some Clarification needed (Spellstrike in particular)
But on the whole Good Job on The Magus.
