You seem more interested in the int hybrid.. and if done correctly it can be a powerful and still hard to kill build in PvP.. you will lack the defense of the shield but spear hybrids hit harder than swords like anything else two handed weapons do deal more dmg-
I personally have a Str fire glaive hybrid -- I put in about 27 points into int that pushed my phy balance up to 102 -- could probably go to 104 or 105 if i got perfect str on my 72-77 set and my magical balance is 52-- maybe possible for 54 or so-- I hit harder than glaivers with weapons 3 or more +'s higher than me with same masteries .. but i do crit just a little less hard-- still very effective crits though- I stuck with garments so nukers have a horrible time with me
lol sorry to ramble on-- but just think about str hybrid too-- int hybrid isnt the only hybrid that does well
