3 Newbie Troll Questions.

Out of interest, what're you using the Whelps for?

In all honesty, I'd go with dropping the Whelps altogether, get double Northkin Shamans or somehow get in a Troll Bouncer (Shield Guard and Earth's Blessing are both so useful to Ragnor).

You can buy the extra Whelps, but without a King, you're almost certain to rarely (if ever) use them all. Ten is enough for now IMO.

AFAIK, but I'll have to check it, the status of an upkeep is where the spell is based, not where the spellcaster is based, so if an upkeep is on a model/unit (with 1+ model) in Doomy's CTRL, cost to upkeep is doubled. I think this is to make upkeep owners think about how they use their attachments (the ones that provide free upkeeps, that is). Someone may need to confirm or correct this though...

Oh, I can totally understand why...

However, speak to most Troll players and say (in a vacuum) 'fury management' and they won't really care too much (i.e. they'll laugh, 'fury management?! what is this sorcery?!'). I don't mean to be derisive when I say that, but particularly for Ragnor, there isn't any real need for it.

Turn one Earth's Blessing and dump everything else in the stone (because your upkeeps will already be out) and rile/run to generate six. Turn two feat and tank shots/charges ('cos Ragnor's feat is used for that purpose), counterpunch with some souped up beasts, force to max across the board, played right you'll be up on attrition by quite a margin that anything that does get killed, you can reave the Fury at your discretion (or not because of From the Grave). You leave your opponent in the difficult position of 'do you have enough to hurt my battlegroup? and if you do, which is unlikely, can you afford to leave any alive?' Assessment of the board state allows you to choose which ones you need a full activation's worth of work from and which can Frenzy. Those that Frenzy can deal a bit of solid damage and get even further in your opponent's face (if they do move/charge).

You have the potential to generate 22 Fury, a friend of mine runs a Ragnor list with an M-King, double EBDT's, double Bouncers and an Axer (no whelps in the base list), which comes in at the same total and he uses the Whelps generated by damage on the King to heal/contest/charge block, not for fury management. Whelps help to reduce the risk, certainly, but if fury management is the primary reason you're taking them, there are better things to spend your free slots/points on. That said, Tim Banky is taking two lots of Whelps with his Borka2 list at WTC, but there is quite a gap between Fury 5/6, admittedly.

In so saying, I'd recommend playing variants and one lot of Whelps (I believe they'll only truly be necessary on post-feat turn). Have you considered Dhunian Knot?
