Some Suggestions/Improvements After Playing TFT
Just giving some feedback based on both my own play and watching others' games....
Early Item Distribution Normalization/Compensation Items feel just as important/powerful as champions and upgrades. This actually feels like an appropriate level of power, where you feel like they are impactful, unlike DAC where often items feel underwhelming or insignificant. However, the early item distribution (particularly off the first 3 creep waves) can make or break a team's early and sometimes midgame. That you could potentially end up with 0 items if unlucky and 9 if lucky makes for some games to majorly hinge off those first 3 rounds. Normalizing the percentages of item drops or- taking a page from DAC- offering a compensation item (consumable?) every X numbered neutral monsters without an item drop would make this early game RNG more even.
Opponent Level on the Sidebar This is more of personal preference, but at least early in TFT's development, it feels hard to gauge when to proceed into midgame (Particularly the breakpoints for levels 5, 6, and 7.) To reference again DAC: You could have people pressing up levels early or holding back to econ; knowing this information was key to deciding your own levelling vs saving gold. Knowing at a glance- without having to go to each board each turn- if for example half your opponents have gone to Level 6, so you might want to level to 6 yourself to keep on pace with them, could be majorly useful for those who are trying to judge the pace of their current game. Often times without this knowledge- particularly if you are holding back for econ- the information about who is pushing forward in levels or not is gleaned too late: when they're already on your board fighting you.
At-A-Glance Star Level Differentiation As suggested by many people, a means of more clearly conveying Star Level for units- such as Skins- would go a long way towards clarity. Size is a hard benchmark to judge at a glance; most times I just have to assume all my opponent's pieces past Round 2-6 are 2 stars. Sure you can click on pieces and see information on them, but that's either time prohibitive to do between rounds (going to your opponents' boards), difficult to do during combat (because of moving pieces), or information gleaned too late. Being able to quickly assess the enemy teams' star levels at a glance helps keep players informed to make their own decisions more accurately.
Stats in Profile/Match History or the TFT Submenu A personal want, but I (and many others) are "stat monkeys." I love the Year in Review each year, and on a smaller scale I like being able to look at the graphs and stats of my past games. Currently, TFT does not provide stats about games- even rudamentary ones- in the client. You can't see your past games' results, your team lineups, etc. anywhere outside the end-game screen. Having these appear in your match history (or even a subsection of the TFT Menu) would be greatly desired.
