As for RuneScape gold herblore, Mod Pi: Together with reguards[sic] into herblore and prayer, the present in sport incentive'[sic] the top tiers offer you push the participant up to now above their grade it had been creating balancing bosses to be challenging difficult[sic]. If you balanced to get a player without these fosters, anyone with turm + ovl could locate the struggle a stroll at the park. If you balanced for a player with these boosts then you pretty much made them a requirement. This was far from ideal as the fans that prayer and potions give you need to be regarded as a boost along side[sic] that which you had rather than as vital as getting the best weapon in game.
With their existing strengths though, turmoil is capable of providing you the exact same boost as the gap between barrows and nex gear/choatics[sic] and overloads are capable of giving you the same increase as the gap between godwars gear and nex gear/chaotics. So they are far from miniature boosts.
I can understand that compared to this present values these look like huge nerfs but the inherent problem is really that turm/ovl is too powerful now and has been abandoned in that state for too long. It seems to me when the cb update launches summoning won't be as easy as herblore, but after the summoning rework it ought to become a lot better.
Disregarding everything above, I would suggest using the xp on summoning because summoning benefits more out of the bonus xp, as you save both money and time collecting charms. You know how formerly summoning always had a 1.1x multiplier on bonus xp weekends unlike other abilities so as not to be unbalanced? Well, this time it's just like any other ability, so I'd take advantage of that if I needed OSRS Gold For Sale summoning xp.
