Families have seen their damage output increased, but then nerfed after it was found titans were hitting too hard on certain bosses. I'm not sure RS gold how the situation is. In the words of mod rathe, Summoning has been largely set to one side for now since we believe it needs a whole Evolution of Summoning update to itself to do it justice.
However, the fact that everything will be multicombat will make it more effective than currently. As for herblore, Mod Pi has reguards[sic] on prayer and herblore and prayer, the in-game bonus's that the top tiers give you push the player to a level so high above their level that it made managing bosses and difficult.
If you balanced for one player who didn't have these boosts, anyone with the turm + ovl will have a blast in the park. If you were balancing for a player who has these boosts, then they were pretty much the standard. This wasn't ideal as the cheap OSRS GP buffs that prayer or potions grant you should be seen as an increase in the things you already had instead of more important than having one of the greatest weapons in the game.
