Currently in the process of leveling up a Frostalf Thane for solo RvR. Wanted to get some feedback on possible 50 specs and RA choices. Starting points 5 str 5 con 10 dex 10 piety

Couple of specs I am considering, any feedback is appreciated.

50 Stormcalling \\ 42 Shield \\ 29 Hammer \\ 26 Parry
48 Stormcalling \\ 50 Shield \\ 29 Hammer \\ 13 Parry
46 Stormcalling \\ 50 Shield \\ 29 Hammer \\ 19 Parry

RAs for 4L2:

MOB 3 \ WOC 1 \ ST 1 \ Purge 1 \ IP 1 \ wp1 \ lw1

IP2 \ Purge2 \ lw1 \ wp1

MOB 2 \ MOParry 2 \ Purge 2 \ WP2 \ Either WOC, IP 1, or ST 1 for last 5 points

Decisions....decisions

personally i'd got with the 42 shield and higher parry. add + 11 to both, and your fine. as far as RA's one could argue many different points about that. granted one could argue with the spec i suggested, but it gives you the most chance for defense.

While soloing %90 of your enemies are dual wielders. 8 more shield spec gives you %2 block rate against dual wielders, %4 against others. So 50 shield feels like a waste.
29 weapon at least, but not more than 39
42 shield
44-50 sc
rest parry
They all work.

I wouldn't even try to play solo visible without IP2. WoC1 is good for poping stealthers (which is most of your enemies are) and ST1 isn't that bad too. Most enemies run away to avoid it's stun but you will be free to cast since they don't all use dd charges to rupt you. Puge1 is a must imo. You also need WP1 to make your spells able to crit if i'm not wrong. So I would go for IP2 / WoC1 / ST1 / Purge1 / WP1 / LW1 at 4L2. Then you should add mastery of parry3 and purge3 at higher RRs.

st 1 is a must!
