Looking at daily-less strikers I've played (1st level): A fire elementalist, and two scouts, one axe, one sword.
to hit:
Elementalist: +5 vs nads
axe scout: +7 vs ac
sword scout: +10 vs ac
I start with to hit to because its kinda huge: My sword scout missed on only 3 total attacks (after heroic effort and other rerolls) over 10+ 3-4 round encounters, swinging twice every round. Both the elementalist and axe scout miss a lot. This lowers their actual effectiveness, and so despite high damage, they can actually have lower damage per round than my sword scout did.
fire elementalist bolt: 1d12+1d6+8=10-26 dmg at will
fire elementalist ignite:1d10+8 = 9-18 per hit targets (usually two for me, so 18-36)
axe scout: 1d10+1d6+7+7 = 16-30 (8-17 if only first hits) at will, +2 with ca
Sword scout: 1d8+1d4+6+6=14-24,+2with ca, +2 with aspects
not too far off, really. Plus scouts get some great aspect bonuses. But if the el-sorc hits 3+ targets, its obvious that el-sorc starts winning...
encounter:
elementalist: +1d10 (per hit) and hit one more target (with the +1d10)! If the extra hit hits that's an effective damage increase of 2d10+1d12+1d6+8 on elemental bolt! Also, I get to shift.
axe scout: +1d10
sword scout: +1d8
......if anything is out of line for elementalists, it's the encounter power.
They are a potent striker with their at wills, but I think its close enough (though I've definitely felt at times I was doing too much damage, I think I did more with my sword scout), but the encounter nova they can do is unmatched by any thing a scout, thief, slayer or other essentials striker can hope for. Then again, I've missed both targets several times with my encounter, leaving me with only my killer at-wills to use for the rest of the fight
Just my thoughts.
