Undecided on class

[D4rtagnan]

I am about to join a Pathfinder game. My character is starting at lvl 2 and I cannot decide what to make.
Currently the party make up is magus, alchemist, cleric, wizard, and psion.
What do you all think would complement the party well?

p.s. Don't give me "play what you feel like" line. I 'feel' like something that works well with the party.

Sounds like you could use more frontline defenders, and a second healer wouldn't hurt either (pun intended). Paladin sounds like it would do quite nicely. Alternately, since you appear to not have an archer, a switch-hitting Ranger could be great too.

A Paladin would round out the party nicely as a tank. Now if you want to murder mobs try an invulnerable raging barbarian.

A rouge wouldn't be a bad choice either.

before i make reccomendations.

i need to know what basic roles they cover.

Magus, i know is a melee combatant

Psion is a caster, but i need to know what powers he manifests

Wizard is also a caster but i need to know what spells he uses

i need to know whether the cleric is martially oriented, a pure caster or a channel bot and whether he uses positive or negative energy.

i need to know whether the alchemist throws bombs, or uses extracts/mutagens to augment his melee ability.
