Why level 7 tree?
2 strong reasons that justifies the extra cost in sp
- If the mobs don’t die then they start to walk away towards the dps, however, having a longer tree with a whoping +6 sec(thx to audra) prevents this.
- If you have a short duration tree then your goal is just to make them clustered am I right? How about if you had additional mobs to pull? the addition 4 points in it makes it easier to cluster additional pulled mobs =D
This is just personal experience and I do not see in any reason why you should invest it in other skills like what?- more icebolt? ice pike? Nope. It is as you said, those are just a waste of mana cost.
On gust being a pushing skill, guys lets not forget we have a far better skill called “Energy Bolt”. Easier to target and far better range; Bonus: it doesnt break frozen status
