As far as healing goes, the amount of YOUR healing is increased with wp, per the tooltip. Now, that doesn't work for BoH for some reason, but it does work for BE. Also keep in mind both tactics can crit. BE healing is pretty weird. It goes all over the place, with about 230 wp it's usually around 83 per tick, but it sometimes goes bellow that or even above that, to 90+(not crit). Consider that usually it doesn't heal for the tooltip value (at maxed out tree it's supposed to be 405, and there are 4 ticks), you would need to have a decent amount of wp for that I guess. At around 230 wp it still heals about 20% less than tooltip. Now I am no expert in healing obv, and I don't know how formulas work, but I just find it odd. So I am wondering, are these tactics working as intended, especially BoH?
Another thing I wanted to talk about with the players, is the idea of healing tanks/warriors (more popularly known as paladins in rpg games). I believe there is an intention here in the case of SM, to make it somewhat a 'paladin' archetype, in addition to his dps tank archetype. We all know how great they are in a dps spec, but what about his tanking support spec? I think it's very underwhelming. Don't get me wrong, SM can be quite tanky with snb, but I'm talking more about these healing tactics. As people probably know, the healing is pretty lackluster when it comes to smaller scale (I doubt anyone in their right mind would spec them). In scs I can do about 10-20k healing (maybe more if it lasts long), but keep in mind this is obviously not direct healing. We are talking about HoTs here, basically fluf healing. For rvr, BoH is not so bad I guess, since it heals every ally who hits the enemy (WoH is in that tree so you can just spam it to put the buff on everyone around you). Maybe that's the reason wp doesn't increase the healing, but I think that would be pretty lame.
Now someone might think "20k for a tank? Not THAT bad.", but when you realize how much you gimp yourself for that and that it's HoTs, it becomes clear that it's quite disappointing. If you want any 'decent' amount of healing, you need to increase your wp somehow. It would be stupid to do it with rr, so I used gear, specifically rings and cloak (green gear from merchants). I didn't find heal crit to be useful since you need to pretty much max it out with rr to make any difference, which is obviously very bad.
In total, there are 3 pieces of gear that you can buy from merchants that have willpower on them, they will give you 65 wp. It would probably be better to use talis for that tho, since gimping yourself with that cloak and rings just sucks even more (I lose precious morale gain and ini). So if you took 6 20wp talis, that's 120 wp + 98 base wp gives you 318. I'm still pretty sure that even at that amount, your 'healing' wouldn't change dramatically. If I did that, I would lose some 1k hp, since I have wounds now for rvr purposes. And now you see how gimping it is. Losing 1k hp in rvr is quite a big deal for a tank (with morales flying everywhere, and destro morales being op ofc) and the return it would have is very minimal.
So you gimped yourself completely, and your healing is still not much better, if at all. Remember that BoH doesn't even increase with wp. The only change you did is mildly increase the healing for your party, congratulations I guess

Now with all that in mind, what do you think about this? Is the idea of healing tanks something you like? Is there anything that can be done to change this, or do you think it works as intended, and giving healing to tanks would break balance/make them op? I personally love the idea of paladins as classes. It would give you more possibilities, more specs to play. You can have gear and bonuses concentrated towards it, maybe even abilities. I hope I convinced people that the current situation leaves much to be desired. The same thing applies to BO, who only has one healing tactic in his right tree.
