So this is my first 4th edition campaign I'm going to be playing in. My DM has quite a few restrictions which is making it difficult for me to build a character and I'd appreciate some advice from the board. My group currently has no strikers and there are currently 5, maybe 6 other people playing in it. The group has 2 defenders, 2 controllers and 1 leader and potentially 1 more defender so the groups damage output is relatively low. So I'd like to make a striker for the group also this group is pretty optimized but the DM has set restrictions. No dragon magizine content, nothing from eberron or forgotten realms. I can use anything else except those i was looking at making a doppleganger from the monster manual. I know they changed them to changelings in eberron but my DM says i can use the doppleganger from the monster manual. Also we have a stat array of 16,16,14,13,12,8. Our dm doesn't like people having starting stats of 20. Also we are starting at 1 then time dropping at level 4 and then continuing at level 11. It can be a glass cannon i don't mind(prefer ranged class, also hybrids look really cool). Thank you for any advice.
