Fighter used to be a nice 2 level dip for any class wanting to see some melee, but now with Armour Mastery it makes sense to go one more if you want to use heavier armour types. I agree that Level 4 is nice for Weapon Specialisation, but only if your Feat selection will allow it and mine is pretty tight. :)
I really like Archetypes as I am a big fan of being able to customise a character to suit a specific charactisation. I know that it also makes it much easier for people to build overpowered machines of death and destruction, unable to be touched my mortal man, but for someone like me who enjoys creating weird class/race combinations, having that extra little bit of versatility is a fun addition. I honestly don't believe that any of my characters are overpowered for their customisation, as I build "Characters", not Deathbots... :)
Feel free to peruse my Aliases, as every one is an actual character created to play (although in some cases they may have been created for games that never eventuated). :D
And then I'm back. My computer suddenly died on me for no discernible reason other than to piss me off. Bonus: my harddrive permanently expired, costing me a couple of months of PhD dissertation progress. Capital! That'll teach me to back my stuff up more often.
EDIT: 127 new posts!? Really?? Better get to work...
