I disagree with starting points in str being a complete and total waste - unless you're twinked, wearing heavy armor while also scrounging up some loot will absolutely kill you. Sta is just for those who <will> raid and max out the other abilities, if you're not going for that and got to claw your way up, a few points in STR as a DE/Human/Erudite isn't all that bad.
The problem with the SK is that you need so many stats that you'll simply have to prioritise some. AC -> HP -> the rest should be a good guideline, as your spells will always get you the aggro you need to tank. So investing heavily in sta isn't a bad move, especially when you'll be twinked or handed down some basic gear with STR on it.
In this regard, picking a human, ogre or troll is in my opinion the easiest way to go. Spend a few points in dex/agi as an ogre and the rest on sta and you're good to go. As a troll, you can do whatever you want and as a human, you don't suffer the xp penalties and horrible faction that the evil races have while maintaining absolutely mediocre stats that you let do whatever you want.
In the end, ogres and trolls have the superior stats but the combined penalty of race+class might wear you down. I know it nearly killed me on live when I played a troll SK
