Reason why i choose Charisma over Dexterity is because Charisma gives you Companion influence and a little of recharge speed, which is way better than some severity and movement speed from dexterity.
Powers/feats:
Feats we are going to use are: Relentless Speed, Bloodspiller, Overpenetration, Steel Slam and Relentless Battlerage.
Reason why you’re going to use Not so fast:

Indomitable Battle Strike

Watermelon Sorbet OR Major or superior flask of potency, wild storm elixir, squash/pumpkin soup and m15 3% damage potion which you can get from swag bags from campaign(Acquisitions incorporated) store.
Also you can use one of these: Tymora coin, Chain of scales or pocket pet. I prefer to use chain of scales, you can get additional critical severity from it.
With mod 16 changes you’re going to use companions that add stats you don’t have capped yet, in any other case go with power ones.
Current best summoned companion is bulette pup due to it’s increased power stat(and some others of course). The reason why I don’t have it yet is because I’m too poor to buy one right now, so I’m sticking with my mod 8 ioun
Noncombat:
In combat with tenser:
Stats you’re going to get before you start stacking power are:
118k CA to get 100% bonus when you have combat advantage
68k Critical Strike to get 50% crit chance(max)
70,5k Armor Penetration (2,5k more due to our overpenetration feat)
68k accuracy
If you catch them all you can start stacking your power in any possible way.
You can find some usefull things like caps for each level, most companion stats and a lot of other things.
