What are good stats to use for a tank and also dps paladin
For tank paladin or for tanks in general,I'd say go for determination since determination increases your damage and healing the more you get hit and the more damage and healing you deal the more the aggro and blood lust since it heals you by % of damage and healing dealt as well as vitality which is HP and tenacity so you won't get high wound complexity and would be easy to get healed.
For DPS ,I'd say go for proficiency and brutality since they give good damage as well as some tenacity as it makes you do additional damage when you have no wound complexity and since in many cases a DPS class won't get hit so you won't accumulate wound complexity and be able to benefit from this stat.
And even if you want some DPS on tank you can put some brutality and proficiency along with determination but I'd say focus determination most of all.
