Yeah not enough ppl go bigger they are, pretty broken talent in a lot of situations, gives crazy burst heal if you take the lifesteal talent (plus it's bugged right now to work on evasion i believe). For laser vs. odin there are a couple of things to consider, but you can figure out the best choice but thinking it out step by step. Odin gives aoe and instantaneous nuke, you give up on your passive but gain 25% res, very good if you are the main backline, there are long fights, and they are divey and very good on static objectives like infernal. Benefits of laser include bodyblocking (great on dshire for example), retaining your passive, and a really strong 20 talent, but it's an easy ult to waste due to low range and health. Good for interrupt obj like cursed or standing ones like sky temple (though odin is very good on map styles like sky temple). Lots of ppl pick laser to retain their passive and that's fine. Bloodlust/odin isnt talked about enough, put neosteel coating on top of that and he's too beastly
