In the present, despite their strengths the turmoil could be capable of giving you similar boost to the difference between barrows and gear and chokeatics. They are capable of RuneScape gold giving you an identical boost to the different between godwars gear and nex gear/chaotics. Also, they're far from small boosts.

I can understand that compared to current levels they seem like massive nerfs but the issue is that turm/ovl's power is at a high level and has been in that condition for too long.

It is my impression that when the cb update goes live, summoning might not be as useful like herblore. However, following the revamp of summoning it will improve.

Disregarding everything above I'd recommend making use of the summoning xp due to the fact that summoning makes more out of the bonus xp, as it saves money and time in gathering charms. Did you know that summoning would always have a 1.1x multiplier on weekends of bonus xp unlike other skills to avoid to be imbalanced? Now, this is just like any other skill, and I'd use the summoning the xp.

I believe it's time I get the hang of that skill. At the moment I'm currently 63 in the skill. The only knowledge I have with that skill (I mean performing it, not actually the exp for getting a higher level) it's about five times in a solo.

I've got 100 tokens, and that's why I'm not able to gain any rewards from Dungeoneering (I really want a bonecrusher for hunter/combat training). The way I gained my level of proficiency in buy rs07 fire cape the skill is by tears of guthix, penguin points, lamps from sof and quests. I had a bit of a cheating experience through the skill until I'm a dungeoneering noob at level at 63.
